By default all the streams are mapped to all links after controller is
reset which causes stream to be broadcast on all the links.

This patch resets the stream-link mapping after controller reset. The
stream is mapped later to the appropriate link as part of stream setup.

In order to achieve better DMA performance and reduce download time for
firmware and library, it is recommended to disable dynamic clock and
power gating. In some scenarios, DMA may wait to accumulate more data and
last chunk of data never gets completed if dynamic clock and power
gating is kept enabled.

This patch adds support to disable/enable dynamic clock and power gating
and use it during firmware and library download.

Platform registration happens in probe work handler whereas machine
device is registered during skl_probe. This sometimes results in cpu
dais not found if the work handler is sufficiently delayed due to system
load, even with deferred probe of machine driver.

So move machine device registration after registering platform.

When NHLT endpoint is present for a SSP then we create clock for that SSP.

MCLK is consistent across endpoints and configuration for an SSP, so query
only for first endpoint for an SSP.

For SCLK/SCLKFS, the best fit is queried from the NHLT configurations which
matches the clock rate requested. Best fit is decided based on below:

1. If rate matches with multiple configurations, then the first
   configuration is selected.

2. If for a selected fs and bits_per_sample, there are multiple endpoint
   configuration match, then the configuration with max number of
   channels is selected. So, the user has to set the rate which fits
   max number of channels

So we create a platform device and pass clock information parsed as
platform data.
