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.
