Subject: [PATCH v3 1/3] irqchip: Pass platform_device pointer to init_cb
It makes sense to just pass device_node for callback in IRQCHIP_DECLARE
case, but not so much for IRQCHIP_PLATFORM_DRIVER one, because
platform_driver probe/init usually needs device pointer for various
purposes, e.g. resource allocation, service request, device prefixed
message output, etc. Create a new callback type irqchip_init_cb_t which
takes platform_device pointer as parameter, and update the existing
IRQCHIP_PLATFORM_DRIVER users accordingly.
