On the RF3290,RF5360,RF5370,RF5372,RF5390,RF5392
radio frontends, the VCO calibration can be
controlled via the RFCSR3 register. The current
code uses the RFCSR30_RF_CALIBRATION constant to
enable the calibration, however that belongs to
the RFCSR30 register. Although the values of the
constant is correct, but using that for another
register is confusing.

Add a new definition for the VCO calibration enable
bit of the RFCSR3 register and use that in the
relevant places in order to avoid confusions.

The patch contains no functional changes.

GPIO register fields indicating the GPIO pin value and the fields
indicating the direction.
Start using a unified naming scheme for the GPIO register fields:
	- <csr>_VAL<x> for fields indicating the GPIO pin value.
	- <csr>_DIR<x> for fields indicating the GPIO pin direction.

About 70% of the chips with revision RT5390R initialize incorrectly, using
the auxiliary antenna instead of the main one. The net result is that
signal reception is very poor (no AP further than 1M).

This chipset differs from RT5390 and RT5390F by its support of hardware
antenna diversity. Therefore antenna selection should be done
differently, by disabling software features and previously selected
antenna.

This changeset does just that, and makes all RT5390R work properly.

This is based on Ralink's 2012_03_22_RT5572_Linux_STA_v2.6.0.0_DPO
driver.

rt2800pci is suffering from beacon skew in AP mode. Some powersaving
clients (like VOIP phones) are getting into trouble after some time
when the beacon skew is getting too big.

The ralink legacy drivers contain a function that indicates that the
beacon timer is off by 1us per tbtt. And this function works around
that by reducing the beacon interval for every 64th beacon transmission
by 64us (the smallest possible value). Do the same in rt2800pci.

This allows proper powersaving when rt2800pci is used in AP mode.

rt2800 devices should adjust their tx power in accordance with the
eeproms temperature calibration values. Add a new driver callback
gain_calibration that is called every 4 seconds.

The rt2800 gain calibration routine simply runs the tx power
configuration that takes care of calculating the temperature
compensation delta.

We don't need to synchronize the calls to rt2800_config_txpower
as they should all happen from mac80211's single threaded workqueue.
