This tells the driver to which SoC UART to direct the UART traffic
send over eSPI from host.

help
Use minimum RAM buffer size by default but allow applications to
override the value.
Maximum OOB payload is 73 bytes.
config ESPI_FLASH_BUFFER_SIZE

default 256
depends on ESPI_FLASH_CHANNEL
help
Use maximum RAM buffer size defined by spec but allow applications
to override if eSPI host doesn't support it.

help
Enable Slave Attached Flash eSPI driver. SAF depends upon ESPI XEC driver
and flash channel.
