Patch series adds support for legacy interrupt in pci-j721e. There are
two HW implementations of legacy interrupt controller, one specific to
J721E and the other for J7200/AM64.

In both these implementations, the legacy interrupt is connect to pulse
interrupt of GIC and level to pulse is handled by configuring EOI
register.
