Bluetooth: hci_bcm: Add Lenovo Yoga Tablet 2 830 / 1050 to the bcm_broken_irq_dmi_table 



The DSDT for the Lenovo Yoga Tablet 2 830 / 1050 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.
