[PATCH] clk: tegra: use _clk_pll_disable from _program_pll

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

_program_pll() was dropping the PLL's lock and calling clk_pll_disable().
clk_pll_disable() does nothing but acquire the same lock and call
_clk_pll_disable(). So, remove the lock manipulation code, and just call
_clk_pll_disable() directly instead.

Mike, this also will need to go through the Tegra tree; just looking for
any review/ack from you. Thanks.
