Subject: ramips/mt7621: drop the timer recalibration patch

We've been carrying this patch for many years [1], in order to fix a timer
calibration issue on MT7621. Turns out, after retesting with a recent kernel
(Linux 5.10), the system works perfectly fine without it (no rcu_sched stalls
or inconsistent BogoMIPS values across CPUs).

Manually refreshed:
322-mt7621-fix-cpu-clk-add-clkdev.patch
323-mt7621-memory-detect.patch
