ARM: tegra: clock: Fix Tegra3 clock locking

Added locking for non-atomic access to shared registers for the
following clocks:
- secondary PLL dividers
- audio doublers
- cml (sata/pcie) clock controls

Added locking for peripheral clocks secondary reference counting
(register access is atomic, but some clocks may share an enable bit).

Updated comments for external output clocks (shared access already
protected).
