set_var_mtrr() and get_free_var_mtrr() don't need to be guarded
against various stages. It just complicates code which lives
in a compilation unit that is compiled for multiple stages by
needing to reflect the same guarding. Instead, just drop the
declaration guard. earlymtrr.c is still just compiled for earlier
stages, but if needed it's easy to move to a mtrr_util.c that
is compiled for all stages.

Therefore, provide an option, PARALLEL_MP_AP_WORK, that allows

Certain platforms have a poorly performing SPI prefetcher so even if
accessing MMIO BIOS once the fetch time can be impacted. Payload
loading is one example where it can be impacted. Therefore, add the
ability for a platform to reconfigure the currently running CPU's
variable MTRR settings for the duration of coreboot's execution.
The function mtrr_use_temp_range() is added which uses the previous
MTRR solution as a basis along with a new range and type to use.
A new solution is calculated with the updated settings and the
original solution is put back prior to exiting coreboot into the OS
or payload.
Using this patch on apollolake reduced depthcharge payload loading
by 75 ms.
