irqchip/gicv3-its: Refactor ITS DT init code to prepare for ACPI
In order to add ACPI support we need to isolate ACPI&DT common code and move DT logic to corresponding functions. To achieve this we are using firmware agnostic handle which can be unpacked to either DT or ACPI node. No functional changes other than a very minor one: 1. Terminate its_init call with -ENODEV for non-DT case which allows to remove hack from its-gic-v3.c. 2. Fix ITS base register address type (from 'unsigned long' to 'phys_addr_t'), as a bonus we get nice string formatting. 3. Since there is only one of ITS parent domain convert it to static global variable and drop the parameter from its_probe_one. Users can refer to it in more convenient way then.
