ARM: tegra: clock: Don't BUG on changing an enabled PLL
When updating the CPU PLL frequency, keeping the PLL enabled avoids ramping the PLL all the way down and back up again. Remove the BUG_ON in tegra2_pll_clk_set_rate to allow the rate to change while the PLL is enabled. Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Colin Cross <ccross@android.com>
