[PATCH 1/4] ASoC: SOF: amd: Fix for reading position updates from stream box.

[PATCH 1/4] ASoC: SOF: amd: Fix for reading position updates from stream box.

[V sujith kumar Reddy]

By default the position updates are read from dsp box when streambox
size is not defined.if the streambox size is defined to some value
then position updates can be read from the streambox.

[PATCH 2/4] ASoC: SOF: amd: Fix for selecting clock source as external clock.

[V sujith kumar Reddy]

By default clock source is selected as internal clock of 96Mhz
which is not configurable. Now we select the clock source to
external clock (ACLK) which can be configurable to different clock
ranges depending on usecase.
