clk: tegra: Mark timer clock as critical
The timer clock feeds the timer block, which, among other things, is
used to drive the SOR lane sequencer. Since the Tegra timer driver is
not enabled on 64-bit ARM, nothing currently claims that clock and it
gets disabled by the common clock framework at late_init time.
Given the non-obvious dependencies, the timer clock can be considered
a critical part of the SoC infrastructure, requiring its clock source
to be always on.
