[PATCH 04/24] Documentation: DT bindings: add more chip compatible strings for Tegra timers

[Paul Walmsley <paul@pwsan.com>]

Add compatible strings for the timer IP blocks present on several
Tegra chips.  The primary objective here is to avoid checkpatch
warnings, per:

http://marc.info/?l=linux-tegra&m=142201349727836&w=2

N.B. The nvidia,tegra20-timer compatible string is removed from the
nvidia,tegra30-timer.txt documentation file because it's already
mentioned in the nvidia,tegra20-timer.txt documentation file.
