drivers: interrupt_controller: Refactor GIC configurations

The current GIC configuration scheme is designed to support only one
specific type and version of GIC (i.e. GIC-400 that implements the
GICv2 interface).

This commit adds a set of GIC version configuration symbols that can
be selected by the SoC configuration to specify which version of GIC
interface is implemented in the SoC.

interrupt_controller: gic: Support multiple GIC versions

The current GIC driver implementation only supports the GIC-400, which
implements the GICv2 interface.

This commit refactors the GIC driver to support multiple GIC versions
and adds GICv1 interface support (GICv1 and GICv2 interfaces are very
similar).
