msm: camera: utils: Add support for multiple IRQ lines per device

Browse Source 
Update SOC util to be able to parse multiple irq names from DT and,
request, enable, disable multiple irq lines per soc.

All IRQ lines per SOC will have the same handler but different data,
so ISR will have their own private data to differentiate source of irq
in the same handling function.
