    b43: don't duplicate common PHY read/write ops

b43_phy_copy() accesses phy_read and phy_write directly and will fail
with some phys. This patch fixes the regression by using the
b43_phy_read() and b43_phy_write() functions which should be used for
read and write access.

This should fix this bug report:
