x86: GEODE: MFGPT: Use "just-in-time" detection for the MFGPT timers

Browse source 
There isn't much value to always detecting the MFGPT timers on
Geode platforms; detection is only needed when something wants
to use the timers.  Move the detection code so that it gets
called the first time a timer is allocated.
