OFW doesn't support operation at 1 and 1.2 GHZ on XO-4

Quanta keeps requesting support for running the main cores at 1 GHz
on XO-4. Currently they run at 800 MHz on XO-4 A2 motherboards.
I'm told that this requires firing up the second PLL, as the processors will
no longer be synchronous to the memory interface.
As with XO-1.75, we have a GPIO (#3, w. jumpers on the motherboard) which
should select the processor frequency (0 for 1 GHz, 1 for 1.2 GHz).
Quanta will have A2 boards with 1.2 GHz processors for testing by the
end of next week (8/30/2012).
