Add a quirk to limit AHCI MSI vectors to one
In 10.1-RELEASE the default number of MSI vectors used was changed from one
to as many vectors as the HW supports.
This change resulted in an ahci timeouts regression when running on AMD
SB7x0/SB8x0/SB9x0 hardware, so its now limited to 1 MSI by default using
this new quirk.
MFC after: 2 weeks
