Subject: [PATCH v4 17/17] svm: Allow AVIC with in-kernel irqchip mode

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

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