Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.
The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.
This patch addresses the problem for reads only, as coreboot is not
expected to require to write long chunks into SPI devices.

This patch uses the new bootblock_mainboard_early_init() hook to run the
UART pinmuxing on rk3288-based boards before initializing the console.
This allows us to get rid of the hacky second console_init() call in
bootblock_soc_init(). We can also simplify the pinmux selection a bit
since we know that a given board always uses the same UART (still keep
an assert around to be sure, though).

On most platforms, enabling the console and exception handlers are
amongst the very first things you want to do, as they help you see
what's going on and debug errors in other early init code. However, most
ARM boards require some small amount of board-specific initialization
(pinmuxing, maybe clocks) to get the UART running, which is why
bootblock_mainboard_init() (and with it almost all of the actual
bootblock code) always had to run before console initialization for now.
This patch introduces an explicit bootblock_mainboard_early_init() hook
for only that part of initialization that absolutely needs to run before
console output. The other two hooks for SoC and mainboard are moved
below console_init(). This model has already proven its worth before in
the tegra124 and tegra132 custom bootblocks.

This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.
Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.
Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

Ideally only the header offset should be specified (and even that
could be derived from the bootblock size). But this is a more generic
problem to be addressed with different architectures' image layout
requirements in mind.

Our CBFS header offset on rk3288 was very low and overlapped with the
end of the bootblock on recent Pinky builds. This can create all kinds
of fun effects like BSS variables suddenly being initialized to
something else than zero, in an effect that jumps somewhere else for
every slightest code size change.
This patch moves the CBFS header offset up a bit and the CBFS ROM offset
down (because there's really no point in leaving such a large gap). This
resolves our immediate booting problems, and I'll also start on a patch
to add further checks somewhere that catch these overlaps in the future.

TEST=Created a Pinky image from the exact same commit version as the
official 6443.0.0 build, with a KERNELREVISION string of the exact same
length as the builder (which for some arcane reason is different than
running emerge locally, shifting the whole bootblock around with it).
Confirmed that I saw the same "Not enough room for another
sub-pagetable!" hang, and that this patch fixes it.

LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns
the real VCC10 regulator on or off. We tried setting it to 3.3V since it
matches the VCC33_SYS voltage on the input of that regulator. However,
we didn't notice that the LDO only supports going up to 2.5V.
This patch changes the voltage to the allowed maximum, which should
still work fine as an enable line (and is the same value used by the
kernel). This removes an assertion error in the ramstage.
Also change the PMIC driver to assert maximum VSEL values based on the
LDO, because the lower-voltage ones support one more setting. (LDO3 is
actually listed to only go up to 0b1111 in the manual, and has a weird
jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I
don't know if that's a documentation error or what they were smoking
when they designed that, but we don't need to care for now.)
