armv8: fsl-layerscape: Add NXP LS2081A, LS2041A SoC support

The QorIQ LS2081A SoC has eight 64-bit ARM v8 Cortex A72 cores and
is built on layerscape architecture. It is 40-pin derivative of
LS2084A (non-AIOP personality of LS2088A). So feature-wise it is
same as LS2084A. LS2041A is a 4-core personality of LS2081A.
