wifi: mt76: mt7925e: fix too long of wifi resume time

Browse Source 
The mt7925e takes a long time to resume in platform resume
scenarios. This is due to the mt7925 reconfiguring the tx
power for each wifi channel during resume. By streamlining
the process and removing redundant power configurations,
the resume time for the mt7925 can be shortened.
