[patch V2 06/25] KVM: arm64: Use ktime_get_snapshot_id() to snapshot CLOCK_REALTIME

[Thomas Gleixner]

From: Thomas Gleixner <tglx@xxxxxxxxxx>

ktime_get_snapshot() is replaced by ktime_get_snapshot_id() which allows to
request a particular CLOCK ID to be captured along with the clocksource
counter.

Convert the usage in kvm_get_ptp_time() over and use the new
system_time_snapshot::systime field, which holds the system timestamp
selected by the CLOCK ID argument.

No functional change intended.
