[lightning-ln882h] Fix GPIO interrupt support (#326)

Browse Source 
* fix interrupt handling for the ln882h

- all GPIOS can generate interrupts
- added calls to NVIC_SetPriority/NVIC_EnableIRQ/NVIC_DisableIRQ

* fix clang formatting error

* only call NVIC_DisableIRQ if no other gpio is using an interrupt

* fix (again) clang-format errors

* add IRQ capability on all pins

* don't bother with NVIC_DisableIRQ

* use pin->gpio instead of interruptNumber, use macro GPIO_GET_PORT for clarity

* Mark interrupts as supported for the LN882H
