If I'm reading the TRM right, these are CAM_MCLK/CAM_MCLK2 in the
RST_DEV_X register. Is the TRM simply inconsistent in the naming of
these clocks, or is there some other inconsistency?

Does it make any sense to
s/tegra_clk_vi_sensor_8/tegra_clk_vi_sensor_114/ and put the definition
into the table in clk-tegra-periph.c instead? I suppose if this clock
definition is specific to Tegra114 there's not much point, so this is
probably fine. Hopefully the new tegra_clk_vi_sensor_8 lasts longer than
just Tegra124...
So overall, I think:
