[PATCH v6 0/2] J-Core timer support

[Rich Felker]

Updated to include changes requested by Thomas Gleixner. Aside from
minor style improvements, the main changes are moving from the old cpu
notifier framework for cpu starting to the cpuhotplug framework. Since
the new framework does not easily facilitate multiple driver instances
without significant additional code, and since there is presently no
need for multiple instances, the (now-only-nominal) support for
multiple instances was removed; this simplifies some of the code. Use
of the full 64-bit clocksource was also replaced by 32-bit to avoid
expensive (non-native, software) 64-bit arithmetic in hot paths.

I've also removed a comment about Linux implementation details from
the DT binding document since it's not actually part of the bindings.

Finally, driver was made conditional in Kconfig to avoid it showing up
in configurations where it's not relevant.
