revert cpld gateware to backwards compatible
...
* to a strictly backwards compatible (to v1.3 proto rev 8) implementation for v1.4 hardware
* exception: OSK (which is high now and was low in v1.3)
* to make the transition to a future v1.4-specific gateware and ARTIQ
coredevice driver smoother and is a fallback.

cfg: add div to configure clock divider
...
Keeping the two bits at 0 will ensure backwards compatible default operation.
Other settings force the divider to the respective value.
* 0: en_ad9910: divide-by-4, ~en_ad9910: divide-by-1
* 1: divide-by-1
* 2: divide-by-2
* 3: divide-by-4
