kernel: Set CONFIG_RCU_CPU_STALL_TIMEOUT=21
...
The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.
This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

kernel: move two symbols to the generic kconfigs
...
CONFIG_RCU_{NEED_SEGCBLIST,STALL_COMMON} are set basically everywhere. Move them
to the generic kconfigs. And resort the generic kconfigs while at it.

kernel: disable CONFIG_RCU_EXPERT and friends
...
Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.
Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.
