ENGR00132153 sgtl5000: do not enforce symmetry if rate is unknown

The CS42888 can only playback or record the multiple 44k streams,
as there is only the 22.579MHz Osc on the board. Enable the
ALSA plugin or ASRC when try to playback or record multiple 48k
streams.

1)There is still pop noise sometimes when start/stop/pausing a playback,
this patch is used to further reduce the pop noise.
2)Enter low power mode(power down DAC) when there is no playback for 5 seconds.
3)Modify amixer controls "Speaker Playback Switch" and "Headhpone Playback
Switch"

Changes such that DAC Mux will only affect whether the headphone
output gets connected to the DAC or Line in.
The previous implementation of the DAC Mux allowed the dapm power
level of the sgtl5000 to be affected whether audio was playing or
not. It also controlled the an internal osc which had no effect
since it didn't affect whether mclk was turned on.

wm8580 is using regulators that can't change state. The
regulator driver doesn't handle this case well so it crashes
during regulator_bulk_enable. Eventually this will be fixed in the
regulator driver. For now, remove regulators from list in
wm8580 driver.
Fix spi_rw err. hw_write needs to return transferred data length.

Move regulator control into codec drivers.
Move codec platform data to machine layer.
Remove unused fields from mxc_audio_platform_data.
soc multiple audio cards support:
dai_list is a list for all registered codec/cpu dais.
One codec/cpu dais can't be registered twice, so move the
cpu dai registering into imx-ssi.c/imx-esai.c
Fix ak4647_read_reg error.
Put ssi/esai mode in the cpu_dai private_data.
sgtl5000: Fix the power for MX35
1. MX35 vddio and vddd are directly connected to
external 3V3. It has no regulator control.
2. sgtl5000 needs some time to be ready after vdda
is switched on so msleep(1) is added before regiter
read/write.
3. On MX35 platform, vdda is from VCAM.

commit 48e3cbb3f67a27d9c2db075f3d0f700246c40caa upstream.
This patch fixes a bug where "virtual" registers were being written to the ac97
bus. This was causing unrelated registers to become corrupted (headphone 0x04,
touchscreen 0x78, etc).
This patch duplicates protection that was included in the wm9713 driver.

PLL was not being enabled when it was not bypassed. This patch
enables the PLL when it is used. Additionally, it disables the PLL
when it is bypassed.
Without this patch, the audio on TI DM646x EVM and DM355 EVM
does not work properly. The bit clocks and the frame sync signals
from the codec are not correct and hence the playback/record are faster
than usual for most sample rates. The reason for this was that the PLL
was not enabled when it was not bypassed.
Tested on DM6467 EVM, playback tested on DM355 EVM.
