Subject: [PATCH v2] bluetooth: hci_bcm: enable IRQ capability from node

Actually IRQ can be found from GPIO but all platorms don't support
gpiod_to_irq, it's the case on amlogic chip.
so to have possibility to use interrupt mode we need to add interrupts
field in node and support it in driver.

Signed-off-by: Guillaume La Roque <glaroque@...libre.com>

sorry for noise,

v2 is for rebasing on master branch
