[PATCH 1/2] b43: HT-PHY: init: add missing PHY mask/set ops

[PATCH 1/2] b43: HT-PHY: init: add missing PHY mask/set ops

[Rafał Miłecki]

MMIO hacks were used to trick ndis&wl. For example following:
 phy_read(0x0280) -> 0xffff
phy_write(0x0280) <- 0xff3e
***
 phy_read(0x0280) -> 0x0000
phy_write(0x0280) <- 0x003e
was translated to mask 0xff00 and set 0x3e.
