Leonard Crestez 768e1a8e09 soc: imx8mq: Read SOC revision from TF-A ...

SOC revision on older imx8mq is not available in fuses so on anything
other than B1 current code just reports "unknown".

TF-A already handles this by parsing the ROM and exposes the value
through a SMC call. Call this instead of reimplementing the workaround
in the kernel itself.
