[PATCH 03/10] arm: imx: Drop custom lowlevel_init

Marek Vasut
2022-12-22T00:47:30Z

The custom lowlevel_init implementation is no longer necessary, since
it is responsible for routing and trapping SErrors in U-Boot in EL2,
which is implemented in common code since commit:
6c7691edd55 ("armv8: Always unmask SErrors")
