elog: Probe for SPI flash on bus indicated by Kconfig variable
This replaces a hard-coded bus number of 0 with a Kconfig variable,
CONFIG_BOOT_MEDIA_SPI_BUS. This removes an assumption made for x86
where this value is always 0 and makes it easy to add support for
other platforms where the bus number for the backing SPI flash is
more arbitrary.
BUG=none
BRANCH=none
TEST=tested on Nyan (bus=4) and Link (bus=0)
