Revert "Add drivers to allowfm radio to work on sixth sense port"

This reverts commit b7145c911125123631b2b1857eae30903fe50b70.
msm: memutils: memcpy, memmove, copy_page optimization

Preload farther to take advantage of the memory bus, and assume
64-byte cache lines.  Unroll some pairs of ldm/stm as well, for
unexplainable reasons.

Future enhancements should include,

- #define for how far to preload, possibly defined separately for
  memcpy, copy_*_user
- Tuning for misaligned buffers
- Tuning for memmove
- Tuning for small buffers
- Understanding mechanism behind ldm/stm unroll causing some gains
  in copy_to_user

msm: memutils: memcpy, memmove optimization

1. To fit 8x26 64-bytes cache line size, we change preload steps as 64Bytes.
2. According to tune result, change preload distance as 5 cache lines.
3. According to tune result, re-arrange the ld/str order as back-to-back
   for copy_from_user.

The markable improvement:
	memcpy : 5%
	copy_to_user : 9%
	copy_from_user : 13%
	memmove : 37%
