fsl_ifc: Add the workaround for erratum IFC A-003399(enabled on P1010)
Issue: Address masking doesn't work properly. When sum of the base address, defined by BA, and memory bank size, defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask CSPRn[BA] bits. Impact: This will impact booting when we are reprogramming CSPR0(BA) and AMASK0(AMASK) while executing from NOR Flash. Workaround: Re-programming of CSPR(BA) and AMASK is done while not executing from NOR Flash. The code which programs the BA and AMASK is executed from L2-SRAM.
