FSP 1.0: Fix CAR issues - broken timestamps and console

FSP 1.0 has a fixed-size temporary cache size and address and the entire
cache is migrated in the FSP FspInitEntry() function.

Previous code expected the symbol _car_data_start to be the same as
CONFIG_DCACHE_RAM_BASE and _car_data_end to be the same as
_preram_cbmem_console.

FSP 1.0 is the only one that migrates _preram_cbmem_console.
Others leave that where it is and extract the early console data in
cbmemc_reinit(). Special handling is needed to handle that.

Commit dd6fa93d broke both assumptions and so broke the timestamp table
and console.

The fix is to use CONFIG_DCACHE_RAM_BASE when calculating the offset and
to use _preram_cbmem_console instead of _car_data_end for the console
check.
