This patch removes hardcoded dma channel value in lpass driver, Now the
dma channel allocation happens in the SOC specific layer. This will
allow different LPASS integrations to use the lpass driver in more
generic way.

This patch attempts to remove the hardcoded i2s port number in lpass
driver. Now the the port number comes from the dai id field.
This will allow other SOCs to use different port numbers on the lpass
driver.

This patch tries to make the lpass driver more generic by moving the
ipq806x specific bits out of the cpu and platform driver, also allows the
SOC specific drivers to add the correct register offsets.
This patch also renames the register definition header file into more
generic header file.

Compile-tests show a warning for the newly added SND_SOC_STORM
symbol:
warning: (SND_SOC_STORM) selects SND_SOC_LPASS_CPU which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_QCOM)
The problem is that it can be selected for COMPILE_TEST on non-QCOM
builds, but the symbols it selects have a dependency.
Dropping the dependencies makes it work without warnings and no
other side-effects, because these are not user-visible.

Although switch () lists the most of existing cases, it's still better
to cover the rest as an error properly.

As the representation of the DSP in the device
tree has changed from a required subnode to an
optional phandle, modify the test for DSP
existence in the LPASS CPU DAI driver,
accordingly.
