[PATCH v2 10/15] arm64: hyperv: Add hv_vtl_configure_reg_page() stub

[Naman Jain]

ARM64 does not support the register page overlay, so provide a stub
that returns false. This pairs with the preceding commit that moved
hv_vtl_configure_reg_page() out of common code into architecture-
specific files.
