Bluetooth: hci_bcm: Add broken-irq dmi blacklist and add Meegopad T08 to it
The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430
wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does
contain a valid ActiveLow GpioInt entry, but the GPIO it points to never
goes low, so either the IRQ pin is not connected, or the ACPI resource-
table points to the wrong GPIO.
Eitherway things will not work if we try to use the specified IRQ, this
commits adds a DMI based broken-irq blacklist and disables use of the IRQ
and thus also runtime-pm for devices on this list.
This blacklist starts with the the Meegopad T08, fixing bluetooth not
working on this hdmi-stick. Since this is not a battery powered device
the loss of runtime-pm is not really an issue.
