The DSDT for the Acer Iconia One 7 B1-750 models (which share
the same mainboard) specifies a IOAPIC IRQ for the HCI -> host IRQ but
this is not correct.
Like the Asus TF103C these tablets use pin 17 of the INT33FC:02 GPIO
controller for the IRQ and this pin is _not_ configured in direct IRQ
mode by the firmware.
Add a DMI match for this, re-using the Asus TF103C gpiod_lookup_table,
to fix bluetooth not working on these tablets.
