Subject: [PATCH] b44: Fix MII interface of the B44 driver

From: Aurelien Jarno <aurelien@...el32.net>

The conversion of the B44 driver to SSB bus added the functions
__b44_{read,write}phy functions that have an argument phy_id. This gives
a way to fix the b44_mii_{read,write} functions used for MII interfaces.

The patch below does that. It allows B44 devices with integrated switch
to be configured from userland.
