hardware: replace VCCPLL regulator with RC network

Browse Source

Having a full regulator on VCCPLL causes the ESD network in the ICE40 to
freak out, dumping VCCPLL into GND and trying very hard to burn out the
regulator.

Replace it with a simple RC filter network, which is less clean but
results in a happier ESD network.
