Logs from Linux' i915 suggest that not even the FSP/GOP takes proper
care of this. The sequence is mostly the same as on older platforms,
with a slightly different configuration of the backlight PWM.
We light the panel up with 50% PWM duty cycle. This often results in
an already rather high perceived brightness, but shouldn't be too
blinding.

The code in cpu/intel/car/romstage.c Does most of the things like
setting up timestamps, stack guards, entering postcar.
A functional difference is that the FSP header is searched for twice
instead of passed from the CAR entry to the C code. When using
C_ENVIRONMENT_BOOTBLOCK this needs to be done anyway (or a special
linker symbol kept across multiple stages is needed, which is likely
not worth the speedup).

With the recent refactoring of memory configuration in
CB:32513 ("soc/intel/cannonlake: Support different SPD read type for
each slot"), meminit_cbfs_spd_index ends up reading SPD from CBFS for
each slot. However, for mainboards that use the same SPD index for
each slot this is unneccessary. This change adds a check to see if
spd_data_ptr is not NULL and current spd index is the same as the last
call to decide if SPD read from CBFS should be skipped.
TEST=Verified that SPD gets read only once on hatch.

Re-add the Kconfig CONSOLE_UART_BASE_ADDRESS. It was lost by accident
on APL at least. It is used outside of soc/intel/ scope, e.g. to con-
figure SeaBIOS.
As we only ever configure a single UART for the coreboot console, we
don't need different addresses for each possible UART. Which saves
us a lot of code.

This moves FSP1.1 to use postcar stage to tear down CAR.
On platforms with USE_GENERIC_FSP_CAR_INC the FSP header is found
during the postcar stage so there is no need to push to save it
in CAR global variables.
On FSP1.1 platforms with an open source CAR implementation (Skylake,
even though it still runs the FSP-T), the
soc/intel/common/blocks/cpu/car/exit_car.S code tears down CAR.
This also uses common functions to set up the MTRR to use after
CAR is torn down.
