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.
