Adds platform structs and #defines required by drivers for
IXP4xx built-in Ethernet and WAN (sync serial) ports.
The actual drivers will reside in drivers/net/arm and
drivers/net/wan and will be submitted separately.

This patch adds drivers for IXP4xx hardware Queue Manager and for
Network Processor Engines. Requires patch #4712 (reading/writing
CPU feature (aka fuse) bits).

Adds functions to read and write IXP4xx "feature" (aka "fuse")
bits, containing information about available/enabled CPU features.
The uncompress.h included by boot/compressed/misc.c resides in
a different space than rest of the kernel and thus can't use
asm/hardware.h (including asm/arch/cpu.h - which, in turn, may use
EXPORTed symbol "processor_id").

Various small at91_udc cleanups:
- Use generic GPIO calls, not older platform-specific ones
- Use gpio_request()/gpio_free()
- Use VERBOSE_DEBUG convention, not older VERBOSE
- Fix sparse complaint about parameter type (changed to gfp_t)
- Add missing newline to some rarely-seen debug messages
- Fix some old cleanup bugs on probe() fault paths
Also add a mechanism whereby rm9200 gpios can drive the D+ pullup
through an inverting transistor, based on a patch from Steve Birtles.
Most UDC drivers supporting a GPIO based pullup should probably have
such an option, but testing it requries such a board in hand!

Currently, only one debounce_interval is introduced for both direct and
matrix keys. This is true in most cases, although the keypad controller
supports different debounce for direct/matrix keys.
Some platforms do require this to be tuned, instead of the default
reset value of 100ms.
Rotary encoder will always use zero debounce time for now to achieve
certain sensitivity.

1. Rotary encoder events can be configured either as relative events

useful on some platform which uses the rotary keys as

direct key can now be specified within the platform data

1. Introduce the "struct pxa27x_keypad" structure for driver specific
information, such as "struct clk", generated matrix key codes and
so on
2. Use KEY() macro to define matrix keys, instead of original 8x8 map
this makes definition easier with keypad where keys are sparse
3. Keep a generated array in "struct pxa27x_keypad" for fast lookup
4. Separate the matrix scan into a dedicated function for readability
and report only those keys whose state has been changed, instead
of report all states
