There are 2 version of QSPI-IP, according to which controller registers sets
can be big endian or little endian.There are some other minor changes like
RX fifo depth etc.

The big endian version uses driver compatible "fsl,ls1021a-qspi" and
little endian version uses driver compatible "fsl,ls2080a-qspi"
