ramips/mt7621: drop the weak reordering patch
In order to fix random hangs on MT7621, we've been selecting
WEAK_REORDERING_BEYOND_LLSC for years [1]. However, these random hangs have been
most likely caused by an oversight in the MIPS implementation of the kernel
memory consistency model, which has already been fixed for some time (and
backported to stable) [2].
Manually refreshed:
321-mt7621-timer.patch
