soc/amd/common: Refactor and consolidate code for spi base
Previously, the spi base address code was using a number of different
functions in a way that didn't work for use on the PSP.
This patch consolidates all of that to a single saved value that gets
the LPC SPI base address by default on X86, and allows the PSP to set
it to a different value.
BUG=b:159811539
TEST=Build with following patch to set the SPI speed in psp_verstage.
