bhyve: Silence ACPI RTC error/warning in Linux guests
ACPI Error: Could not enable RealTimeClock event (20180810/evxfevnt-184)
ACPI Warning: Could not enable fixed event - RealTimeClock (4) (20180810/evxface-620)
Also, please MFC if possible. Thanks.
I'd held off this until looking at Linux source to make sure there weren't any side-effects, but this doesn't appear to be any worse than the RTC's currently unimplemented calendar alarms, so I'll get this in.

Silence ACPI RTC error/warning in Linux guests.
Allow guests to set the RTC bit in the ACPI PM control register.
This eliminates an annoying (and harmless) Linux kernel boot message.
