When using a debug build of the FSP, the FSP-M binary is larger than the
memory region we have allocated for it, so increase the size to make the
binary of the debug build fit in there. Also adjust the VERSTAGE_ADDR so
that it starts right after the the FSP-M memory region.
TEST=coreboot builds now successfully when using a debug version of the
FSP

This reverts commit b90e6fdd25. Latest
releases of PSP does not load PSP verstage on S0i3 resume. Hence no need
to skip PSP verstage on S0i3 resume.

Add the pin definitions for the remote GPIOs and the GPIO pin mux values
for the GPIO mode of those pins. For now, accessing the remote GPIOs is
only supported from the native coreboot code running on the x86 cores
and not from verstage on PSP or ACPI.

TEST=On Majolica with a Cezanne APU configuring GPIO 262 as output and
then toggling that GPIO in an infinite loop in the mainboard's bootblock
code results in GPIO 262 toggling as expected.

Right now the ACPI code doesn't support accessing the remote GPIO block
yet, so don't generate invalid remote GPIO access functions and warn
about those being unsupported.

Some AMD SoCs have a 5th GPIO bank, the remote GPIO bank, which isn't
located right after the 4th GPIO bank, but instead at a different
location inside the APCIMMIO region. A difference to the first 4 GPIO
banks is that the corresponding GPIO MUX registers aren't in a separate
bank, but at the end of the remote GPIO region. So this remote GPIO
region only supports 48 GPIOs with a 32 bit configuration register each
and has the 8 bit GPIO MUX registers beginning at offset 0xc0 in the
remote GPIO region.
For now using the remote GPIOs from verstage on PSP isn't supported. To
support this, it would need to map acpimmio_remote_gpio and update the
pointer like it already does for acpimmio_gpio0, acpimmio_iomux and a
few others.

Currently coreboot for the AMD SOCs only supports accessing the up to 4
main GPIO banks of up to 64 GPIOs each. Some AMD SoCs including Cezanne
have another GPIO bank in the ACPIMMIO region that can contain up to 48
GPIOs beginning with GPIO 256 which is called the remote GPIO bank. The
first 48 DWORDs of that ACPIMMIO bank are the 32 bit wide GPIO registers
and beginning at offset 0xc0 it has the corresponding 8 bit wide GPIO
MUX registers.
