m68k: Remove never used asm/shm.h
m68k's asm/shm.h header has been part of the tree ever since m68k support got added in v1.3.94. (It started as /include/asm-m68k/shm.h and moved to its current location a few years ago.) It seems it was never used: no file ever included it and nothing used the macros it defines. (Actually, from v2.5.46 until v2.6.29-rc3 it was included by m68knommu's asm/shm.h. But that header was just a very thin wrapper for this header and was itself unused too.) This header can safely be removed.

- bits 31..9 are used like this:
- bits 15..9 (SHM_ID) the id of the shared memory segment
- bits 30..16 (SHM_IDX) the index of the page within the shared memory segment
- (actually only bits 25..16 get used since SHMMAX is so low)
- bit 31 (SHM_READ_ONLY) flag whether the page belongs to a read-only attach

-/* format on the sun3 is similar, but bits 30, 31 are set to zero and all
- others are reduced by 2. --m */
