KVM: arm64: Engage NV3 ERET trap elision

Browse source

When running on NV3 HW, always engage ERET trap elision when running
the L1 context, as there is no benefit in not doing so.

An L1 can itself engage trap elision by setting its own view of
HCRX_EL2.NVTGE==1, which will subsequently be honored.
