Possible Handbook Typo

[Bob Van Valzah]

I'm just reading the acpi-debug.html page in the handbook and I see
something that looks suspicious (to my eyes at least).

Section 11.16.3.2 System Hangs (temporary or permanent) advises setting
hint.apic.0.disabled="1" in loader.conf.  Shouldn't hints go
in /boot/device.hints instead of loader.conf?

I'm no expert in this area, so I thought I check it with the ACPI list
before submitting a PR.

	Thanks,
