[PATCH V2 4/4] b43: HT-PHY: init: init BPHY and upload 0x1a table

[Rafał Miłecki]

Signed-off-by: Rafał Miłecki <zajec5 at gmail.com>

BPHY is something partially known from N-PHY.

This 0x1a table with 0xc0 offset is a little tricky. We already upload
something like that earlier, but this is needed to stop radio going crazy
and transmissint crap.

V2: limit line to 80 chars
