[PATCH i-g-t v2] tests/intel/xe_gt_freq: Add a wait after gt reset

[Karthik Poosa]

After reset min and max takes sometime to get set.
So add a wait of 100ms after gt reset before reading
min and max frequencies.

v2:
 - Rename ACT_FREQ_LATENCY_US to SLPC_FREQ_LATENCY_US and use it
   instead of new macro. (Riana)
