x86: GEODE: MFGPT: fix a potential race when disabling a timer
We *really* don't want to be reading MFGPTx_SETUP and writing back those
values. What we want to be doing is clearing CMP1 and CMP2 unconditionally;
otherwise, we have races where CMP1 and/or CMP2 fire after we've read
MFGPTx_SETUP. They can also fire between when we've written ~CNTEN to
the register, and when the new register values get copied to the timer's
version of the register. By clearing both fields, we're okay.
