This patch replaces the error counter with two separate error counters, one for
late dma callbacks, and another for overruns (during recording) or underruns
(during playback). The ioctls TEGRA_AUDIO_IN_GET_ERROR_COUNT and
TEGRA_AUDIO_OUT_GET_ERROR_COUNT now take a pointer to a struct containing both
error counters.

Add a new 'reset' clk op. This can be provided for any clock,
not just peripherals.

nvmap and nvhost will behave improperly if iovmm is not present when
their respective devices are probed; however, the probe ordering depends
on the order the initcalls are made to register the drivers. move
iovmm-gart into subsys_initcall to ensure that it is registered earlier
than other drivers

The OTG driver disables the gadget device when the cable is
removed, so there is no need to check if the cable is plugged
before touching registers.

On suspend, dr_controller_stop disable interrupts and on resume, interrupts
are disabled until dr_controller_run is called, so it is safe to call
fsl_udc_clk_suspend/resume with interrupts and the spinlock unlocked.

The upstream DC needs to be clocked for accesses to HDMI to not hard lock the
system. Because we don't know if HDMI is conencted to disp1 or disp2 we need
to enable both until we set the DC mux.
