ptp/kvm, arm_arch_timer: Set system_counterval_t.cs_id to constant
Identify the clocksources used by ptp_kvm by setting the clocksource ID enum constants. This avoids dereferencing struct clocksource. Once the system_counterval_t.cs member will be removed, this will also avoid the need to obtain clocksource pointers from kvm_arch_ptp_get_crosststamp(). The clocksource IDs are associated to timestamps requested from the KVM hypervisor, so the proper clocksource ID is known at the ptp_kvm request site. While at it, also make the ptp_kvm_get_time_fn() 'ret' variable type int as that's what the function return value is.
