x86: Set BOOT_MEDIA_SPI_BUS
BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based platforms to set up CBFS media. It turns out it can also be helpful for setting up the eventlog which is intended to reside on the same SPI flash as CBFS. Setting it for x86 will allow us to remove an assumption about which SPI bus is used for this flash device. Long term this can go away as we come up with a better abstraction for the eventlog's backing store. This is only intended to help us get from here to there.
