Subject: MIPS: ath79: add common USB Host Controller device
Add common platform_device and helper code to make the registration of
the built-in USB controllers easier on the board which are using them.
Also register the USB controller on the AP81 and PB44 boards.

Subject: MIPS: ath79: Store the SoC revision in a global variable
Knowing the exact revision of the SoC is required to make runtime decisions
in various code paths. We have determined the SoC revision already, so we
only need to store that in a global variable.

Subject: MIPS: ath79: Rename ATH79_DEV_AR913X_WMAC option to ATH79_DEV_WMAC
The ATH79_DEV_AR913X_WMAC option was used to select the AR913x specific
wireless MAC registration code. The registration code now supports the
AR933X SoCs as well. Rename the option to reflect the changes.
Also make the new option depends on SOC_AR933X.
