This cleans up the build process for all architectures, providing a
common place to specify vpath, cflags and build rules for various
common files.

This driver uses the generic GPIO functions and allows per-LED port
and pin configuration. It supports up to 32 LEDs.
Rename SoC-specific LED drivers.
Remove enabled parameter to ao_led_init

This replaces having the single output switch based on a pin value and
allows us to box the device and still fetch raw data.
For now, this will use a special libusb2 program, ao-chaosread, to
pull bits as I haven't figure out how to make linux provide two
/dev entries for one USB device.

To make manufacturing these devices tractable, we don't want to
require a custom firmware load for each device, but we still want a
unique serial number. Fortunately, the SoC provides a 96-bit ID which
we can use.

We have no other way of reporting the software version, so just encode
it in the product ID.

Plug the 'force bootloader' thing onto the board while it's running
and it will generate raw bits instead of running them through the CRC
to whiten. Useful for validating the raw hardware.

These are allocated from the OpenMoko USB vendor ID page and offer a
more 'official' number than from using the 0xfffe space.
