rt2x00: Calculate register offset during compile time

By using __ffs() the register offsets were always calculated
at run-time which all FIELD32/FIELD16 definitions were builtin
constants. This means we can heavily optimize the register handling
by allowing GCC to do all the work during compilation.

Add some compile_ffs() macros to perform the calculation at
compile time. After this each rt2x00 module size is reduced
by ~2500 bytes. And the stack size of several functions is reduced
as well which further limits the number of rt2x00 results in
'make checkstack'.

      * 'net' value is retrieved with the inlined function

On 5761 non-e devices, two problems prevent the administrator from
overriding the WOL settings in the device's NVRAM.

The first problem is that GPIO 0 and GPIO 2 have been swapped.  This

disabled in NVRAM.  The fix is to add a new path for the 5761 that
swaps the two GPIOs in the code as well.

The second problem is that GPIO 1 could not be toggled by the driver
because the GPIO is shared with the debug UART GPIO.  This will prevent
the administrator from being able to turn WOL off if it was enabled in
