realtek: timer: Register enabled scheduler clock
Before calling sched_clock_register(), the timer used to drive the
scheduling clock should already be enabled. Otherwise the kernel log
will show strange time jumps during, and the watchdog might not be
pinged in a timely fashion, resulting in reboots.
[ 0.160281] NET: Registered PF_NETLINK/PF_ROUTE protocol family
[ 78.104319] clocksource: Switched to clocksource realtek_otto_timer
Fixes: 3cc801117118 ("realtek: resurrect timer driver")
