board/freescale/common:QIXIS:Fix magic number usage
QIXIS FPGA layout defines the address of registers but The actual register bit implementation is board-specific, So avoid use of magic numbers as it may vary across different boards's QIXIS FPGA implementation. Also, Avoid board specific defines in common/qixis.h Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
