Changed AES config option to be built-into the kernel.
stmp3xxx_dcp_probe() - Moved Algorithm registration below
platform driver data setting and interrupt request calls.
So that algorithms are registered after the platform data is
set. This is done to make it work with latest linux crypto
API changes.

- Turn off DAC and ADC in ANA_POWER reg during idle.
- Turn on zcd and leave it on. Turning if off dynamically
doesn't save power and can cause a small noise artifact.
- Only need to delay 400mSec if state of VAG bit changes.
- Before record, SOC calls digital_mute to unmute, but does
not call digital_mute to mute again after record.
- After record, SOC skips doing the PREPARE state when powering
down. So make sure VAG and mic bias gets turned off in the
STANDBY state if it hasn't already.

Reading the EDID doesn't work for some boards/monitors/cables and
causes I2C errors that prevent sgtl5000 audio codec from initializing.
This is due to a board error in Babbage. The decision was to disable
the I2C path to the DVI connector. On Babbage 3.0 boards this is done
by bringing a GPIO low. This GPIO tristates the I2C levelshifter. The
code already exists which already does that, this ticket is to disable
code that brings the GPIO high for reading the EDID. That way the
level shifter will remain tristated.

Changed the mxc_nd2 driver to attempt to own its interrupt at the very
beginning of the probe. That way, if the imx_nfc driver has already taken
ownership of the controller, the mxc_nd2 driver won't touch the hardware
registers at all.

Created the structure that contains platform-specific information needed by
the imx_nfc driver.

Enable NFC symmetric mode on MX51. MX51TO2 NFC
working has somelimitation, refer to ENGcm09121.
NFC symmetric mode should be used as for the NFC
clock is 33M vs AXI clock is 133M. The ratio is
1:4, according to ENGcm09121, only NFC symmetric
mode can work, asymmetric mode does not work.

The root cause is that CCGR5 [12 - 13] is defalut set as 00
to save power. ipmux clock will be enabled when MCU read/write
data from AIPS_TZ, while SDMA read/write data from AIPS_TZ can't
enable the ipmux clock when MCU in WAIT mode.
"Bit 12 affects ipmux1 via spare_output_1, and Bit 13 affects
ipmux2 via spare_output_2. The default value of those bits is 11
For the default case, CCM will generate 1 for both spare_output_1
and spare_output_2. If either one of those bits will be set to 0,
then the corresponding output will be set to 0 when system enters
WAIT mode. This will allow system to turn off the IPMUX clocks
in WAIT mode and can be used in LP-APM to preserve the IPMUX power
if no accesses are expected on the IP bus. In run mode the IPMUX
clocks will not be closed and the setting of those bits will not
affect RUN mode."

On Babbage boards there is a collision on the I2C bus between
the audio codec and the dvi port. Reading the EDID from the
DVI leaves the I2C in a funky state, preventing the audio
driver from initializing. The fix for Babbage3.0 boards is to
control the I2C bus level shifter from a GPIO so that the level
shifter is tri-stated by default. When reading the EDID the
level shifter is enabled briefly.

- This fixes pops that happened after audio playback. These pops
were caused by zcd and DAC being turned off.
- Enable zcd and leave it enabled.
- Turn on DAC early, leave it on.
- We were turning on analog sections during first playback, now turn
them on during initialization instead to avoid delay.
