Currently if the source DMA device isn't ready to provide the channels
capable of the SPI DMA transfers, the DW SSI controller will be registered
with no DMA support. It isn't right since all what the driver needs to do
is to postpone the probe procedure until the DMA device is ready. Let's
fix that in the framework of the DWC SSI generic DMA implementation. First
we need to use the dma_request_chan() method instead of the
dma_request_slave_channel() function, because the later one is deprecated
and most importantly doesn't return the failure cause but the
NULL-pointer. Second we need to stop the DW SSI controller probe procedure
if the -EPROBE_DEFER error is returned on the DMA initialization. The
procedure will resume later when the channels are ready to be requested.

For devices with no cache it can make sense to use cache only mode as a
mechanism for trapping writes to hardware which is inaccessible but since
no cache is equivalent to cache bypass we force such devices into bypass
mode. This means that our check that bypass and cache only mode aren't both
enabled simultanously is less sensible for devices without a cache so relax
it.

The SAI has multiple successive FIFO registers, but in some use
case the required dataline/FIFOs are not successive, so need
get such information from dts property "fsl,dataline"
fsl,dataline has 3 values for each configuration:
first one means the type: I2S(1) or DSD(2),
second one is dataline mask for 'rx',
third one is dataline mask for 'tx'.
Also set dma peripheral address and TRCE bits according to data lane.

"fsl,dataline" is added to configure the dataline of SAI.
It has 3 value for each configuration, first one means the type:
I2S(1) or PDM(2), second one is dataline mask for 'rx', third one is
dataline mask for 'tx'. for example:
fsl,dataline = <1 0xff 0xff 2 0xff 0x11>,
it means I2S type rx mask is 0xff, tx mask is 0xff, PDM type
rx mask is 0xff, tx mask is 0x11 (dataline 1 and 4 enabled).

With DSD format, the pinctrl is different compare with
I2S format, because one dataline only has one channel
data, and the codec always mux the LRCLK pin to DSD
data line, and on i.MX8MQ the BCLK pin can route to
codec on DSD case for the MCLK is too high.
Add pinctrl operation that the pinctrl can be switched
on runtime according to the I2S format or DSD format

In order to properly bias headset microphones, there should be a pull-up
resistor between pins HBIAS and MIC2P. This can be an external resistor,
but the codec also provides an internal 2.2K resistor which is enabled
by a register.
This patch enables or disables the internal bias resistor based on a
device tree property.
