ar71xx: fix nondeterministic hangs during bootconsole/console handover
Reconfiguring the UART when the FIFO is not empty may cause the boot to
hang. This hang is extremely suspectible to timing differences; recompiling
the kernel with the same configuration, but different UTS_VERSION
timestamps can yield images that hang more or less often. Sometimes images
are produced that hang reproducibly.
This patch should also make it into one of the next linux-stable releases,
but it's better to get this fixed as soon as possible.
Fixes #21773, #21857.
