ACPI / OSL: Use 'jiffies' as the time bassis for acpi_os_get_timer()
commit 83b2348e2755db48fa8f40fdb791f366fabc0ba0 upstream.
Since acpi_os_get_timer() may be called after the timer subsystem has
been suspended, use the jiffies counter instead of ktime_get(). This
patch avoids that the following warning is reported during hibernation:
