hw/intc/arm_gicv3: GICD_TYPER.SecurityExtn is RAZ if GICD_CTLR.DS == 1
The GICv3 specification says that the GICD_TYPER.SecurityExtn bit
is RAZ if GICD_CTLR.DS is 1. We were incorrectly making it RAZ
if the security extension is unsupported. "Security extension
unsupported" always implies GICD_CTLR.DS == 1, but the guest can
also set DS on a GIC which does support the security extension.
Fix the condition to correctly check the GICD_CTLR.DS bit.
