skylake: Add initial FSP2.0 support
Add Initial pieces of code to support fsp2.0 in skylake keeping
the fsp1.1 flow intact.
The soc/romstage.h and soc/ramstage.h have a reference to
fsp driver includes, so split these header files for
each version of FSP driver.
Add the below files,
car_stage.S:
Add romstage entry point (car_stage_entry).
This calls into romstage_fsp20.c and aslo handles
the car teardown.
romstage_fsp20.c:
Call fsp_memory_init() and also has the callback
for filling memory init parameters.
Also add monotonic_timer.c to verstage.
With this patchset and relevant change in kunimitsu mainboard,
we are able to boot to romstage.
TEST= Build and Boot Kunimitsu with PLATFORM_USES_FSP1_1
Build and Boot Kunimitsu to romstage with PLATFORM_USES_FSP2_0
