Port of a Linux commmit b90dc392212d1153a12eea15cbc6eae352a3c989
No functional change. Move the register defines and other macros from
pcie-designware.c to pcie-designware.h. This is in preparation to split the
pcie-designware.c file into designware core file and host-specific file.
While at that also fix a checkpatch warning.
