xlat: cleanup mmap_flags.in

* xlat/mmap_flags.in (_MAP_NEW): Remove SunOS-specific comment, add
a comment that this is a SPARC-specific constant (from
arch/sparc/include/uapi/asm/mman.h).
(MAP_GROWSUP): IA-64-specific constant (from
arch/ia64/include/uapi/asm/mman.h).
(MAP_INHERIT): Add a comment that this is a SPARC-specific constant
(from arch/sparc/include/uapi/asm/mman.h).
(_MAP_INHERIT): Add a comment that this is an Alpha-specific constant
(from arch/alpha/include/uapi/asm/mman.h).
(MAP_ANON): Remove, FreeBSD-specific constant.
(MAP_HASSEMAPHORE): Rename to...
(_MAP_HASSEMAPHORE): ...this, add a comment that this is an
Alpha-specific constant (from arch/alpha/include/uapi/asm/mman.h).
(MAP_NOSYNC, MAP_NOCORE): Remove.
(MAP_AUTOGROW, MAP_AUTORSRV, MAP_LOCAL): Add a comment that this is
an architecture-specific constant (from
arch/mips/include/uapi/asm/mman.h, arch/xtensa/include/uapi/asm/mman.h).
(_MAP_UNALIGNED): Add a comment that this is an Alpha-specific constant
(from arch/alpha/include/uapi/asm/mman.h).

/*
* XXX - this was introduced in SunOS 4.x to distinguish between
* the old pre-4.x "mmap()", which:
*
* only let you map devices with an "mmap" routine (e.g.,
* frame buffers) in;
*
* required you to specify the mapping address;
*
* returned 0 on success and -1 on failure;
*
* memory and which, and the 4.x "mmap()" which:
*
* can map plain files;
*
* can be asked to pick where to map the file;
*
* returns the address where it mapped the file on success
* and -1 on failure.
*
* It's not actually used in source code that calls "mmap()"; the
* "mmap()" routine adds it for you.
*
* It'd be nice to come up with some way of eliminating it from
* the flags, e.g. reporting calls *without* it as "old_mmap()"
* and calls with it as "mmap()".
