[RFC][PATCH] b43: Comment unused functions lpphy_restore_dig_flt_state and lpphy_disable_rx_gain_override

[Jaswinder Singh Rajput <jaswinder@kernel.org>]

Commenting unused functions lpphy_restore_dig_flt_state and
lpphy_disable_rx_gain_override, may be we need these functions in future.

This also fixed following compilation warnings :
  CC [M]  drivers/net/wireless/b43/phy_lp.o
drivers/net/wireless/b43/phy_lp.c:383: warning: ‘lpphy_restore_dig_flt_state’ defined but not used
drivers/net/wireless/b43/phy_lp.c:891: warning: ‘lpphy_disable_rx_gain_override’ defined but not used
