irqchip/gic: Prepare for adding platform driver
To support GICs that require runtime power management, it is necessary to add a platform driver, so that the probing of the chip can be deferred if resources, such as a power-domain, is not yet available. To prepare for adding a platform driver: 1. Drop the __init section from the gic_dist_config() so this can be re-used by the platform driver. 2. Add prototypes for functions required by the platform driver to the GIC header file so they can be re-used.
