bcma: fix invalid PMU chip control masks
Commit b9562545ef0b ("bcma: complete workaround for BCMA43224 and BCM4313") introduced the wrong masks for setting the chip control registers - the "mask" parameter is inverse. It should be the mask of bits *not* changed, which is admittedly a bit non-intuitive. The incorrect mask not only causes the driver to not work correctly on the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the state persists over a soft reset, causing the next boot to not necessarily see the device correctly.
