Subject: [PATCH v2 15/15] svm: Allow AVIC with in-kernel irqchip mode

Once run-time AVIC activate/deactivate, and PIC and IOAPIC EOI workaround
for AVIC is supported, we can remove the kernel irqchip split mode
requirement for AVIC.

Hence, remove the check for irqchip split mode when enabling AVIC.
