[PATCH 3/6] MIPS: ath79: separate AR913x SoC specific WMAC setup code

[Gabor Juhos <juhosg@xxxxxxxxxxx>]

The device registration code can be shared between
the different SoCs, but the required setup code varies
Move AR913x specific setup code into a separate function
in order to make adding support for another SoCs easier.
