mm/mmap: move common defines to mman-common.h
Two architecture that use arch specific MMAP flags are powerpc and
sparc. We still have few flag values common across them and other
architectures. Consolidate this in mman-common.h.
Also update the comment to indicate where to find HugeTLB specific
reserved values
