[PATCH]: Add HCS12 support in gas

[Stephane Carrez <stcarrez at nerim dot fr>]

Hi!

When I added 68HCS12 support in binutils, I committed the bfd,elf,opcodes part but forgot
the gas part with the new -m68hcs12 option.  Committed on mainline.

	* config/tc-m68hc11.c (md_show_usage): Update usage.
	(md_parse_option): Recognize -m68hcs12.
	(m68hc11_elf_final_processing): Set EF_M68HCS12_MACH flag to identify
	HCS12.
	* doc/as.texinfo (Overview): Document new option -m68hcs12.
