With 6caa5812e2d1 ("KVM: arm64: Use generic KVM xfer to guest work
function") all arm64 exit paths are properly equipped to handle the
POSIX timers' task work.
And with a68773bd32d9 ("arm64: Select POSIX_CPU_TIMERS_TASK_WORK") we
now handle the timers in thread context.
This allows for KVM and PREEMPT_RT to coexist, so update Kconfig to
reflect that.

I guess this could be squashed into 19614b91cc83 ("ARM64: Allow to
enable RT")
Note: I did test this on an Ampere Mt. Jade based machine.
