armv8: fsl-layerscape: Fix "cpu status" command
The core position is not continuous for some SoCs. For example,
valid cores may present at position 0, 1, 4, 5, 8, 9, etc. Some
registers (including boot release register) only count existing
cores. Current implementation of cpu_mask() complies with the
continuous numbering. However, command "cpu status" queries the
spin table with actual core position. Add functions to calculate
core position from core number, to correctly calculate offsets.
Tested on LS2080ARDB and LS1043ARDB.
