Setup of the ASP (audio serial port) was being done as a side-effect of
cs42l42_pll_config() and forces a restriction on the ratio of sample_rate
to bit_clock that is invalid for Soundwire.

The chosen clocking configuration must give an internal MCLK (MCLKint)
that is an integer multiple of the sample rate.
On I2S each of the supported bit clock frequencies can only be generated
from one sample rate group (either the 44100 or the 48000) so the code
could use only the bitclock to look up a PLL config.
The relationship between sample rate and bitclock frequency is more
complex on Soundwire and so it is possible to set a frame shape to
generate a bitclock from the "wrong" group. For example 2*147 with a
48000 sample rate would give a bitclock of 14112000 which on I2S
could only be derived from a 44100 sample rate.

Channel status get and channel subcode get controls relies on data
returned by controls when certain IRQs are raised. To achieve that
completions are used b/w controls and interrupt service routine. The
concurrent accesses to these controls are protected by
struct snd_card::controls_rwsem.
Issues identified:
- reinit_completion() may be called while waiting for completion
which should be avoided
- in case of multiple threads waiting, the complete() call in interrupt
will signal only one waiting thread per interrupt which may lead to
timeout for the others
- in case of channel status get as the CSC interrupt is not refcounted
ISR may disable interrupt for threads that were just enabled it.
To solve these the access to controls were protected by a mutex. Along
with this there is no need for spinlock to protect the software cache
reads/updates b/w controls and ISR as the update is happening only when
requested from control, and only one reader can reach the control.

The SPDIFRX block is clocked by 2 clocks: peripheral and generic clocks.
Peripheral clock feeds user interface (registers) and generic clock feeds
the receiver.
To enable the receiver the generic clock needs to be enabled and also the
ENABLE bit of MCHP_SPDIFRX_MR register need to be set.
The signal control exported by mchp-spdifrx driver reports wrong status
when the receiver is disabled. This can happen when requesting the signal
and the capture was not previously started. To solve this the receiver
needs to be enabled (by enabling generic clock and setting ENABLE bit of
MR register) before reading the signal status.
As with this fix there are 2 paths now that need to control the generic
clock and ENABLE bit of SPDIFRX_MR register (one path though controls, one
path though configuration) a mutex has been introduced. We can't rely on
subsystem locking as the controls are protected by
struct snd_card::controls_rwsem semaphore and configuration is protected
by a different lock (embedded in snd_pcm_stream_lock_irq()).
The introduction of mutex is also extended to other controls which rely on
SPDIFRX_RSR.ULOCK bit as it has been discovered experimentally that having
both clocks enabled but not the receiver (through ENABLE bit of SPDIFRX.MR)
leads to inconsistent values of SPDIFRX_RSR.ULOCK. Thus on some controls we
rely on software state (dev->trigger_enabled protected by mutex) to
retrieve proper values.
