The DAPM pin operations currently require that the specific DAPM context
that the pin being operated in is contained in be specified. With multi
component and especially with the addition of a per-card DAPM context
this isn't ideal as it means that things like disabling unused pins on
CODECs require looking up the CODEC DAPM context.

Fix this by falling back to matching a widget in any context if there isn't
a match in the current context. The code isn't ideal currently but will do
the job.

Currently we allow all DAPM contexts to determine their own bias level.
While this should in general work in most situations and will deliver the
lowest possible power it causes problems for our integration with the
card bias level as we're calling the card bias level functions for each
DAPM context even though they're card wide but don't say which CODEC
we're calling them for. Mitigate against this by forcing everything to
be in the same state.

Since we recently explicitly set the register for registerless widgets
to no register there is no longer any need to special case power updates
for them, we can allow them to be handled with the register compression
code as other widgets are.

As this is the only remaining user of dapm_generic_apply_power() and
dapm_update_bits() also remove those functions.

Update the headphone and line out mixers and PGAs use the same logical
set of register bits and sequencing as the speaker mixer/PGA.

This allows ALSA controls for mute and volume on headphone and line out
to operate correctly.

Per conversation on alsa-devel, earlier datasheets indicated that the
POWER_MANAGEMENT_* register bits 0 and 1 were aliases to ANALOG_* register
bits 0 and 4, and hence only one copy of those bits was programmed.
However, later datasheets corrected this.

Suppose we have:

	cpu_dai
		channels_min = 1
		channels_max = 1

	codec_dai
		channels_min = 2
		channels_max = 2

This is a mismatch that should not happen, however according to the current
code, the result of runtime->hw will be:

		channels_min = 2
		channels_max = 1

We better spot it early. This patch checks this mismatch.

wordsize is used as the textual width of a register address.

regsize is used as the textual width of a register value.

The assignments to these values were swapped. In the case of WM8903, which
has 8-bit register addresses and 16-bit register values, this caused the
register values to be clipped to 2 digits instead of the full 4.

pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1,
but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will
be called immediately, it leaves prtd->dma_ch initialized with -1,
and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered
via SDL.

This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and
cleans prtd->params, so now it works properly.
