[for-8.2,0/2] arm/kvm: use kvm_{get,set}_one_reg

The kvm_{get,set}_one_reg functions have been around for a very long
time, and using them instead of open-coding the ioctl invocations
saves lines of code, and gives us a tracepoint as well. They cannot
be used by invocations of the ioctl not acting on a CPUState, but
that still leaves a lot of conversions in the target/arm code.

target/mips and target/ppc also have some potential for conversions,
but as I cannot test either (and they are both in 'Odd fixes' anyway),
I left them alone.

Survives some testing on a Mt. Snow.
