Bring the WM8350 IRQ API more in line with the generic IRQ API by
masking and unmasking interrupts as they are requested and freed.
This is mostly just a case of deleting the mask and unmask calls
from the individual drivers.
The RTC driver is changed to mask the periodic IRQ after requesting
it rather than only unmasking the alarm IRQ. If the periodic IRQ
fires in the period where it is reqested then there will be a
spurious notification but there should be no serious consequences
from this.
The CODEC drive is changed to explicitly disable headphone jack
detection prior to requesting the IRQs. This will avoid the IRQ
firing with no jack set up.

This is done as simple code transformation, the semantics of the
IRQ API provided by the core are are still very different to those
of genirq (mainly with regard to masking).

The DAPM widgets are now insntantiated by the core when creating the card
so there is no need for the individual CODEC drivers to do so.

snd_soc_init_card() is always called as the last part of the CODEC probe
function so we can factor it out into the core card setup rather than
have each CODEC replicate the code to do the initialiastation. This will
be required to support multiple CODECs per card.

It's the 8th enum of a zero indexed array. This is why I don't let
new drivers use these arrays of enums...

More and more devices feature PLLs and FLLs with the ability to select
between multiple input clocks. In order to better support these devices
a new argument, source, has been added to the set_pll() configuration
API. Using set_clkdiv() is often difficult due to the need to stop the
PLL/FLL before any reconfiguration can be done.

If the requested FLL configuration is the one we're currently running
in it's at best pointless to reconfigure the FLL.

For best performance the DAC sloping stopband filter should be enabled
below 24kHz and not enabled above that so remove the user visible
control for this and do it autonomously in the driver.

We need to check only if the WM8350 is master and only when starting

Considering the fact that most cpu_dai or codec_dai are using a same
'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better
made a pointer instead, to make sharing easier and code a bit cleaner.
The patch below is rather preliminary since the asoc tree is being
actively developed, and this touches almost every piece of code,
(and possibly many others in development need to be changed as
well). Building of all codecs are OK, yet to every SoC, I didn't test
that.

Many codec drivers were implementing cookie-cutter copies of the function
that adds kcontrols to the codec.
This patch moves this code to a common function snd_soc_add_controls() in
soc-core.c and updates all drivers using copies of this function to use the
new common version.

The WM8350 is an integrated audio and power management subsystem which
provides a single-chip solution for portable audio and multimedia systems.
The integrated audio CODEC provides all the necessary functions for
high-quality stereo recording and playback. Programmable on-chip
amplifiers allow for the direct connection of headphones and microphones
with a minimum of external components. A programmable low-noise bias
voltage is available to feed one or more electret microphones.
Additional audio features include programmable high-pass filter in the
ADC input path.
This driver was originally written by Liam Girdwood with further updates
from me.
