b43: HT-PHY: implement spurious tone avoidance

On N-PHY it's also done after TX power fix, so it was easy to spot.
Unfortunately the MMIO logs I have from ndsiwrapper include channels
1-12 only, so enabling code for 13 and 14 is just a N-PHY-based guess.

b43: HT-PHY: move TX fix to the separated function

On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix
function which iterates over available cores. It matches our HT-PHY code
which means it's probably also some TX fix.

Merge tag 'nfc-next-3.10-1' of git://git./linux/kernel/git/sameo/nfc-next

Samuel Ortiz <sameo@linux.intel.com> says:

This is the first NFC pull request for 3.10.

The 2 features we have with this one are:

- An LLCP Service Name Lookup (SNL) netlink interface for querying LLCP
  service availability from user space.
  Along the way, Thierry also improved the existing SNL interface for
  aggregating SNL responses.

- An initial LLCP socket options implementation, for setting the Receive
  Window (RW) and the Maximum Information Unit Extension (MIUX) per socket.
  This is need for the LLCP validation tests.

We also have a microread MEI build failure here: I am not sending this one to
3.9 because the MEI bus code is not there yet, so it won't break for anyone
else than me.

NFC: llcp: Add cleanup support for unreplied SNL requests

them from the list of pending requests. The timeout is fixed to an
arbitrary value of 3 times remote_lto.

When not replied, the local LLC broadcasts NFC_EVENT_LLC_SDRES nl events for
the concerned uris with sap values set to LLCP_SDP_UNBOUND (which is 65).

When the SNL reply is received, a NFC_EVENT_LLC_SDRES event is sent to
