intel: update common and FSP cache-as-ram parameters
Instead of just passing bits, tsc_low, tsc_high, and an
opaque pointer to chipset context those fields are bundled
into a cache_as_ram_params struct. Additionally, a new
struct fsp_car_context is created to hold the FSP
information. These could be combined as the existing
romstage code assumes what the chipset_context values are, but
I'm leaving the concept of "common" alone for the time being.
While working in that area the ABI between assembly and C code
has changed to just pass a single pointer to cache_as_ram_params
struct. Lastly, validate the bootloader cache-as-ram region
with the Kconfig options.
