mm: move MAP_SYNC to asm-generic/mman-common.h
This enables support for synchronous DAX fault on powerpc
The generic changes are added as part of b6fb293f2497 ("mm: Define
MAP_SYNC and VM_SYNC flags")
Without this, mmap returns EOPNOTSUPP for MAP_SYNC with
MAP_SHARED_VALIDATE
Instead of adding MAP_SYNC with same value to
arch/powerpc/include/uapi/asm/mman.h, I am moving the #define to
asm-generic/mman-common.h. Two architectures using mman-common.h
directly are sparc and powerpc. We should be able to consloidate more
#defines to mman-common.h. That can be done as a separate patch.
