arm-common: gic-v3: Forward pending SGIs to virtual queue on enable
Analogously to gic-v2: When enabling Jailhouse, Linux may have some SGIs pending that have to be taken off the physical interface and forwarded to the virtual one. Otherwise, we would lose them or even confuse Jailhouse because it expects SGIs to be injected virtually only (done on interception of GICD_SGIR). Based on original patch by Peng Fan.
