User reports an issue in Ubuntu about the device switch upon playback.
We find the FLL will disalbe when switching headphone to speaker.
The pulseaudio will stop the headphone and close its power. Then,
it just opens the speaker and turn on its power. Therefore,
the supply of system clock does the OFF event and disables FLL.
But the FLL doesn't enable again when the speaker powers on.
The patch adds the recovery of system clock to enable FLL again
for this case. And it covers the case that system clock from MCLK.

"HV" and "VREF" will be powered up when jack type detection process is
started and will be powered off when jack type detection process is finished.
It will generate an unexpected interrupt signal when they are powered
up during the capture process. Codec driver will do the jack type detection
process and we can't capture properly before the jack detection process is
finished. This patch will not power off the "HV" and "VREF" widgets if
headset is detected and it will solve the unexpected interrupt issue. As a
result, it will also solve the silence data captured at the beginning in
headset mic recording issue.

SSM2602 driver is broken on recent kernels (at least
since 4.9). User space applications such as amixer or
alsamixer get EIO when attempting to access codec
controls via the relevant IOCTLs.
Root cause of these failures is the regcache_hw_init
function in drivers/base/regmap/regcache.c, which
prevents regmap cache initalization from the
reg_defaults_raw element of the regmap_config structure
when registers are write only. It also disables the
regmap cache entirely when all registers are write only
or volatile as is the case for the SSM2602 driver.
Using the reg_defaults element of the regmap_config
structure rather than the reg_defaults_raw element to
initalize the regmap cache avoids the logic in the
regcache_hw_init function entirely. It also makes this
driver consistent with other ASoC codec drivers, as
this driver was the ONLY codec driver that used the
reg_defaults_raw element to initalize the cache.
Tested on Digilent Zybo Z7 development board which has
a SSM2603 codec chip connected to a Xilinx Zynq SoC.

Add Texas Instruments's PCM1789 DAC support.
It is a simple DAC and does not have many registers.
One particularity about this DAC is that the clocks must be
always enabled. Also, an entire software reset is necessary
while starting to play a sound otherwise, the clocks are not
synchronized (so the DAC is not able to send data).
