[PATCH v4 5/6] arm: dts: am335x-sancloud-bbe-lite: UEFI SPI export

[Paul Barker]

Add properties to the Authenta SPI flash device node to enable access by
a UEFI application using a fixed GUID. Also specify that this device is
JEDEC compatible so that it is correctly initialized when running
`sf probe`.
