Add hw.ahci.force tunable to control whether AHCI drivers should attach
to known AHCI-capable chips (AMD/NVIDIA), configured for legacy emulation.

Enabled by default to get additional performance and functionality of AHCI
when it can't be enabled by BIOS. Can be disabled to honor BIOS settings if
needed for some reason.

MFC after:	1 month
