Commit 61a7b0ec63 ("ArmPkg/Gic: force GIC driver to run before CPU arch
protocol driver", 2018-02-06) explains why CpuDxe should be dispatched
after ArmGicDxe.
To implement the ordering, we should use a regular protocol depex rather
than the less flexible AFTER opcode. ArmGicDxe installs
gHardwareInterruptProtocolGuid and gHardwareInterrupt2ProtocolGuid as one
of the last actions on its entry point stack; either of those is OK for
CpuDxe to wait for.
