tegra: clock: Add checking for invalid clock IDs
The get_pll() function can do the wrong thing if passed values that are out of range. Add checks for this and add a function which can return a 'simple' PLL. This can be defined by SoCs with their own clocks. Signed-off-by: Simon Glass <> Signed-off-by: Tom Warren <>
