xilinx_spips: Move FlashCMD, XilinxQSPIPS and XilinxSPIPSClass

Move the FlashCMD enum, XilinxQSPIPS and XilinxSPIPSClass structures to the
header for consistency (struct XilinxSPIPS is found there). Also move out
a define and remove two double included headers (while touching the code).
Finally, add 4 byte address commands to the FlashCMD enum.
