This introduces a SPI TPM driver compliant with the TCG issued "TPM
Profile (PTP) Specification Revision 00.43" which can be found by
googling its title.
The driver implements both the hardware flow control protocol and the
TPM state machine.
The hardware flow control allows to map SPI based TPM devices to the
LPC address space on x86 platforms, on all other platforms it needs to
be implemented in the driver software.
The tis layer is somewhat superficial, it might have to be expanded
later.
A lot more implementation details can be found in the code comments.
Also, it is worth mentioning that this is not a complete version of
the driver: its robustness needs to be improved, delay loops need to
be bound, error conditions need to propagate up the call stack.

Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.
With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).
This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.
MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.

Update pack and header order and mark the entries as mandatory and
recommended w.r.t. ordering (mandatory = essential for booting,
recommended = okay to change, but this config is tested and known to work).

Since the HTIF is a non-standard interface, and coreboot already has a
8250 driver, I started implementing an 8250 core for spike[1].

In the default (medlow) code model, pointers are loaded with a lui, addi
instruction sequence:
lui a0, 0xNNNNN
addi a0, a0, 0xNNN
Since lui sign-extends bits 32-63 from bit 31 on RV64, lui/addi can't
load pointers just above 0x80000000, where RISC-V's RAM now lives.
The medany code model gets around this restriction by loading pointers
trough auipc and addi:
auipc a0, 0xNNNNN
addi a0, a0, 0xNNN
This way, any pointer within the current pc 2G can be loaded, which is
by far sufficient for coreboot.

Due to USB LDO issue in current steppings, cold reboot needs to be
temporarily disabled. Thus, hard_reset call should be the same as
soft_reset.
Once future steppings are available INTEL_COMMON_RESET can be enabled again.
