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.

utilize it in both apollolake and skylake thereby removing
the need for SoC-specific structres. The new structure is
used for initializing a bus fully as the lpss i2c API is
simplified in that lpss_i2c_init() is only required to be
called. The struct lpss_i2c_bus_config structure is passed
in for both initializing and filling in the SSDT information.
The formerly exposed functions are made static to reduce the
