When the hardware is configured in HT20 mode, noise floor readings for
the extension channel often return invalid values, which keep the
values in the NF history buffer at the hardware-specific maximum limit.
Fix this by discarding the extension channel values when in HT20 mode.

This refactors the noise floor range checks to make them generic,
and adds proper ranges for each supported chip type.

Combine multiple checks that were supposed to check for the same
conditions, but didn't. Always enable fast PLL clock on AR9280 2.0

This patch adds macros at certain places
which could be optimized for multiple register writes.
The performance of ath9k_htc improves considerably,
especially reducing the latency involved in a scan run.

The PLL control computation used to program the AR_RTC_PLL_CONTROL
register varies between our harware so just add a private callback for it.
AR9003 will use its own callback.

The PHY split is easier done in a few steps. First move
the RF ops to the private ops and rename them accordingly.
We split PHY stuff up first for the AR5008 and AR9002
families. There are some callbacks that AR9002 share
with the AR5008 familiy so we set those first, if AR9002
has some different callbacks it will override them upon
hardware init.
