to the other one input port.

Use reserved memory as PCM mode need more memory.
Use ping-pong buffer for PCM LPA playback to avoid underrun.

The buffer is share between A core and DSP. Enlarge it, so A core will
suspend longer when DSP is playbacking audio.

1. Add clk necessary in dsp driver
2. Add renderer type for select sai or esai

Modified parameter msg in dsp, make sure still can transfer right msg
between DSP and user, modified parameter msg in kernel.

Because we don't correctly free resources when an error occurs
on component creation path we can end up with partially initialized
components.
Freeing such partially initialized components most of the time leads
to kernel crashing in pain.
Avoid this by making sure we either:
* return a fully initialized component, comp->active = true
* don't "create" the component at all, comp->active = false

Old implementation uses /usr/lib/imx-mm/audio-codec
to look for codec libraries.
Also this is the patch where Yocto rootfs stores the codec
libraries. So until we align Yocto with the kernel lets
change the driver to use the old path.
