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
