Now that arch/metag/ has been removed, drop a bunch of metag references in various codes across the whole tree: - VM_GROWSUP and __VM_ARCH_SPECIFIC_1. - MT_METAG_* ELF note types. - METAG Kconfig dependencies (FRAME_POINTER) and ranges (MAX_STACK_SIZE_MB). - metag cases in tools (checkstack.pl, recordmcount.c, perf).
