This patch refines OV csi camera reset sequence according to
OV's recommendation:

This patch refines OV mipi camera reset sequence according to
OV's recommendation:
reset --------------------|_____|----------------
                        ->| 1ms |<-

    ->|   5ms   |<-

This change makes the OV mipi camera be at a correct status
after reset, otherwise, the wrong status of OV mipi camera
will reduce the ~2.78V analog camera power to ~2.3V, which
causes random thin colorful lines on OV5642 CSI camera image
as OV5642 CSI camera uses the same analog power.

When ESAI call ASRC for p2p playback. The datawidth may be
changed. The cpu dai would configure the ESAI data width according
to the modified datawidth(output_bits). The type mismatch between output_bits
and cpu dai's switch branch cause cpu dai's hardware parameter set
fail.

Match the type of output_bits to the switch branch in cpu dai's hardware
parameter configuration function.

If LUT 63 is busy and LUTs 0-31 are busy, the epdc_choose_next_lut
function was not correctly selecting an available LUT between 32-62.
Instead, it was returning 0.  This fixes that issue by properly
offsetting the available LUT from the second 32-bit segment of the
64-bit LUT field.

0x0e -- voltage level control; it can adjust the single end data signals;
0x09 -- define pre-emphasis factor;
(it will affect the rise time and fall time of D0/D1/D2);

On MX6 SabreSD board, gpio_0 is muxed to clko to be
audio mclk and camera mclk. 24MHz osc clk is a stable
clock source, which can meet the requirement of audio
mclk and camera mclk. This patch sets clko parent
clock to be clko2 clock so that camera mclk and audio
mclk can source from osc clk.
There are 2 benifits after applying this patch:
1) clko's original parent clock(pll4_audio_main_clk)
can be gated off to save power or used by another
module.
2) ov5640/ov5642 camera most settings can reach
claimed 15fps or 30fps with no human eye recognizable
video quality downgrade.
