Add CLOCK_EVT_FEAT_DYNIRQ to allow the IRQ could be runtime set affinity
to the cores that needs wake up, otherwise saying core0 has to send
IPI to wakeup core1. With CLOCK_EVT_FEAT_DYNIRQ set, when broadcast
timer could wake up the cores, IPI is not needed.
After enabling this feature, especially the scene where cpuidle is
enabled can benefit.

To prevent misunderstanding, use TIMER_IRQ_CLEAR instead of TIMER_IRQ_EN
in function sun4i_timer_clear_interrupt.

The license information clearly states GPL version 2 only. The extra text
which excludes warranties is an excerpt of the corresponding GPLv2 clause
11.
So the SPDX identifier covers it completely.

Newer Allwinner SoCs have different number of interrupts, let's add
different compatibles for all of them to deal with this properly.

The suniv (new F-series) chip has a timer with less functionality than
the A10 timer, e.g. it has only 3 channels.
Add a new compatible for it. As we didn't use the extra channels on A10
either now, the code needn't to be changed.
The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer.
Register sun4i_timer as sched_clock on it.

In order to unify the names in this directory, let's rename the driver to be
prefixed with timer-*
