staging: r8188eu: we only need one struct bb_reg_def for path a

The r8188eu driver does no longer access rf path b registers via
PHYRegDef.

Change the PHYRegDef array in struct hal_data_8188e to a single
variable that holds the register addresses for rf path a. Remove
the initialisation of path b register addresses.
