DSP modes are documented in the data sheet but not enabled in the driver.
The work-around already implemented for DA7218/9 is also required to
make sure the bit clock handling in DSP modes follows ASoC conventions.

Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

The driver now supports ACPI based initialisation as well as DT
and old pdata methods. However the FW data handling still uses
DT specific calls to read firmware data (of_property*) so for
ACPI based initialisation the FW data will only be set to default
values. This patch updates the FW handling to use device_property*
calls instead so that both ACPI and DT are handled as expected.

In the SRM lock check section of code the '&' bitwise operator is
used as part of checking lock status. Functionally the code works
as intended, but the conditional statement is a boolean comparison
so should really use '&&' logical operator instead. This commit
rectifies this discrepancy.

Currently the handling of the PLL in the driver is a little clunky,
and not ideal for all modes. This patch updates the code to make it
cleaner and more sensible for the various PLL states.

Key items of note are:
 - MCLK squaring is now handled directly as part of the sysclk()
   function, removing the need for a private flag to set this feature.
 - All PLL modes are defined as an enum, and are handled as a case
   statement in pll() function to clean up configuration. This also
   removes any need for a private flag for SRM.
 - For 32KHz mode, checks are made on codec master mode and correct
   MCLK rates, to avoid incorrect usage of PLL for this operation.
 - For 32KHz mode, SRM flag now correctly enabled and fout set to
   sensible value to achieve appropriate PLL dividers.

When the codec is DAI clk slave, and the SRM feature of the PLL
is being used, the enabling of the DAI should occur only after
the PLL has locked to the incoming WCLK. This update adds checking
to the the DAI widget event, so it waits for SRM to lock. There is
also a timeout if that lock doesn't occur within a given time.

For CODEC controls snd_kcontrol_chip() currently returns a pointer to the
CODEC that registered the control. With the upcoming consolidation of
platform and CODEC controls this will change. Prepare for this by introducing
the snd_soc_kcontrol_codec() helper function that will hide the implementation
details of how the CODEC for a control can be obtained. This will allow us to
change this easily in the future.

The patch also updates all CODEC drivers to use the new helper function.
