fsl_ifc: Add the workaround for erratum IFC-A002769 (enable on P1010)
Issue:
The NOR-FCM does not support access to unaligned addresses for 16 bit port size
Impact:
When 16 bit port size is used, accesses not aligned to 16 bit address boundary
will result in incorrect data
Workaround:
The workaround is to switch to GPCM mode for NOR Flash access.
