The patch is to manage HSD feature for power saving. The detail is to
disable HSD feature after the headset detection is done. When the jack
is inserted, the HSD feature will be enabled again.

nau8825 driver restricts the sample rate with over sampling rate, but
currently it barely bails out at hw_params with -EINVAL error (with a
kernel message); this doesn't help for user-space to recognize which
rate can be actually used.
This patch introduces the proper hw constraint for adjusting the
available range of the sample rate depending on the OSR setup, as well
as some code cleanup, for improving the communication with
user-space. Now applications can know the valid rate beforehand and
reduces the rate appropriately without errors.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

There is no pull-up resistor at IRQ line where it connects from
the codec to SoC. When booting, the signal of IRQ pin will keep low
which makes the SoC invoke the ISR repeatedly because the IRQ is
registered trigger low. It will not stop until the codec sets up
the interruption and pulls the signal high. In the patch,
nau8825 will internally pull the signal to high at booting in case
the fake interrupts happen.

The sequence of crosstalk measurement is not robust. The driver
add more protections to make it stronger. The improvements as follows:
(1)Give backup table the default value. The values are the same
with the default of hardware registers. The impact will decline
once restoring the backup table in the wrong way.
(2)Add xtalk_baktab_initialized flag. The flag can keep the
initiation status of backup table. It helps to backup and restore
the backup-table correctly.
(3)Add cancel parameter in the restore function. The volume ramping
should do in crosstalk DONE state only. Otherwise, the delay action
is not allowed because the restore may happen during the jack
eject interruption.
(4)Add xtalk_protect condition check before scheduling work in ISR.
It makes sure the semaphore hold during the crosstalk measurement.
The sequence is still under protection from playback interference.

After reviewing the crosstalk protection, there are two flaws at
semaphore control. The first one is that the semaphore releases are
not enough; and the other is that down_interruptible has an risk to
make the ISR sleep.
Therefore, the driver add more releases before the funcitons return.
Take down_trylock to replace down_interruptible. The ISR can control
the protection as well and never sleep by semaphore.

which can simplify the codec function. The platform may not
need this funciton and reduce the potential risk. Therefore,
We change the property "nuvoton,crosstalk-bypass" to
"nuvoton,crosstalk-enable". The crosstalk measurement is enabled
if the property is set. Otherwise, it is disabled. Besides,
add more condition in the entry point of the crosstalk sequence
