        sys/arch/x86/isa/clock.c: revision 1.43

Check if RTC is disabled only in virtualized environments.

On a real PC, bits 0-5 may be used for the date alarm function,
causing RTC failure to attach and
a "WARNING: no TOD clock present" warning in the boot log.

Verified no regression on QEMU/MICROVM by imil@
