The wireless MAC of the AR933x SoCs uses different base address, and
requires different setup code.

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.

This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.
