b43: Add LP PHY Analog Switch Support
The current verison of b43 uses "b43_phyop_switch_analog_generic" for A,
G and LP phys.
According to the spec, this is the wrong behaviour for the LP PHY
(see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore )
While no problems on the x86 plattform where seen, this leads to a crash
on the BCM5354 SoC (MIPS 32 LE plattform).
This patch implements the analog switch for LP PHYs according to the
specs. It fixes the crash
