[PATCH] arm64: arch_timer: Fix the lack of set_next_event* for workaround of Cortex-A73 erratum 858921

[Kunkun Jiang]

The patch a38b71b0833e moves the programming of the timers from
the countdown timer (TVAL) over to the comparator (CVAL). This
makes it necessary to read the counter when setting next event.
However, the workaround of Cortex-A73 erratum 858921 does not
set the corresponding set_next_event_phys and set_next_event_virt.
This patch fixes it.

Fixes: a38b71b0833e ("clocksource/drivers/arm_arch_timer: Move system register timer programming over to CVAL")
