Changes cs35l45_get_clk_freq_id() function data type from unsigned int
to int. This function is returns a positive index value if successful
or a negative error code if unsuccessful.
Functionally there should be no difference as long as the unsigned int
return is interpreted as an int, however it should be corrected for
readability.

Link VMON, IMON, TEMPMON, VDD_BSTMON and VDD_BATTMON
to DSP1. The CSPL firmware uses them for the speaker calibration
and monitoring.

Adds "Analog PCM Volume" control with supported values
0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB.
The amplifier can operate either in Speaker Mode or Receiver Mode
as configured by the user. Speaker Mode has four gain options
to support maximum amplifier output amplitude for loud
speaker application. Receiver Mode has further optimized
noise performance while maintaining sufficient output to support
phone receiver application. While configured in Receiver Mode,
the analog PCM Volume control is disabled and
the analog gain is fixed to 1dB.

Adds support for a low-power Hibernation State.
Add support for a low-power hibernation state for the DSP. In
this state the DSP RAM contents are maintained, such that
firmware does not need to be re-downloaded, but the rest of the
chip's register state is lost.
Entry to this state is achieved via the register interface
(either by an external driver using the control port, or the
programmable DSP). Exit from this state is triggered by activity
on device GPIO pins, intended SPI transaction, or I2C
transaction with intended slave address.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This can probably wait for the next merge window, I found a number of
cppcheck warnings that I didn't see in my last checks. The irony is
that the only really important issue found by cppcheck was on one of
my previous DPCM changes (submitted separately as a fix).
cs35l45_remove() always returns zero. Make it return no value which
makes it easier to see in the callers that there is no error to handle.
Also the return value of i2c driver remove callbacks is ignored anyway.
This prepares making i2c remove callbacks return void, too.
