MAINTAINERS: Fix path and add bindings to timers

As spotted by Andreas Färber, the clocksource directory path does not follow
the rule where a maintained directory must end with a '/' character.

Also, the timers devicetree bindings documentation is not mentioned in the
entry, so every submission touching the devicetree documentation misses to
Cc the maintainers of the timers.
