arch/x86: Make postcar TempRamExit call generic
Move the FSP-specific call for tearing down cache-as-RAM out of
postcar.c and replace it with an empty weak function.
This patch omits checking if (IS_ENABLED(CONFIG_FSP_CAR)). The
temp_ram_exit.c file with the real fsp_temp_ram_exit() is only built
when CONFIG_FSP_CAR is true.
