The hardware has a tick counter (constantly incremented every
cycle) and a pps counter (which is the tick counter captured
at the pps edge).

The 32 bit register is split in different fields to speed up
access to the 'in' field. The oe/out fields can't be split because
all writes are 32 bit wide (i.e. no support for byte enable in the
gateware)

Also don't force enable the runner in the e1_platform_led_set
callback.
Due to GPIO shortage, the E1 leds control are multiplexed with
SPI so this adds a method to temporarely stop the runner so SPI
can be used.

Also default build to it since very few people would want to build
firmware targetted to the prototypes ...

Currently only the icE1usb-proto is supported. Adaptation for the
final production hardware is yet to be done.
