MIPS: ath79: add common WMAC device for AR913X based boards
Add common platform_device and helper code to make the registration
of the built-in wireless MAC easier on the Atheros AR9130/AR9132
based boards. Also register the WMAC device on the AR81 board.

MIPS: ath79: add common SPI controller device
Several boards are using the built-in SPI controller of the
AR71XX/AR724X/AR913X SoCs. This patch adds common platform_device
and helper code to register it. Additionally, the patch registers
the SPI bus on the PB44 board.

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.

MIPS: jump label: Add MIPS support.
In order not to be left behind, we add jump label support for MIPS.
Tested on 64-bit big endian (Octeon), and 32-bit little endian
(malta/qemu).

MIPS: Use WARN() in uasm for better diagnostics.
On the off chance that uasm ever warns about overflow, there is no way
to know what the offending instruction is.
Change the printks to WARNs, so we can get a nice stack trace. It has
the added benefit of being much more noticeable than the short single
line warning message, so is less likely to be ignored.

MIPS: Use BBIT instructions in TLB handlers
If the CPU supports BBIT0 and BBIT1, use them in TLB handlers as they
are more efficient than an AND followed by an branch and then
restoring the clobbered register.

MIPS: Add generic support for multiple machines within a single kernel
This patch adds a generic solution to support multiple machines based on
a given SoC within a single kernel image. It is implemented already for
several other architectures but MIPS has no generic support for that yet.
[Ralf: This competes with DT but DT is a much more complex solution and this
code has been used by OpenWRT for a long time so for now DT is a bad reason
to stop the merge but longer term this should be migrated to DT.]
