Marc Zyngier 338f8ea519 KVM: arm64: nv: Accelerate EL0 timer read accesses when FEAT_ECV in use ...

Although FEAT_ECV allows us to correctly emulate the timers, it also
reduces performances pretty badly.

Mitigate this by emulating the CTL/CVAL register reads in the
inner run loop, without returning to the general kernel.
