[U-Boot] [PATCH 1/2][v2] armv8: fsl-layerscape: Add NXP LS2081A, LS2041A SoC support

The QorIQ LS2081A SoC has eight 64-bit ARM v8 Cortex A-72 CPUs 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.
LS2081A has one more similar personality which
has four CPUs: LS2041A
