Subject: KVM: arm64: Use the correct timer structure to access the physical
 counter
Patch-mainline: v5.7-rc1
Git-commit: 76a5db107273b1ad01471e48c49635e2b944a7f4
References: bsc#1133021

Use the physical timer structure when reading the physical counter
instead of using the virtual timer structure. Thankfully, nothing is
accessing this code path yet (at least not until we enable save/restore
of the physical counter). It doesn't hurt for this to be correct though.
