The BCLK divider should be calculated using the parameters that actually

We've been using the oversample_rate previously because in the former SoCs,
the BCLK's parent is MCLK, which in turn is being used to generate the
oversample rate, so we end up with something like this:
So, bclk_div = mclk_rate / sampling_rate / word_size / channels.
And this is actually better, since the oversampling ratio only plays a role
because the MCLK is its parent, not because of what BCLK is supposed to be.
Furthermore, that assumption of MCLK being the parent has been broken on
newer SoCs, so let's use the proper formula, and have the parent rate as an
argument.

- sof_hda_bus_init() calls nothing but snd_hdac_ext_bus_init()

initialized locally like before for avoiding the dependency.

* RFR0..7, Receive FIFO register
struct ipc_message contains fields: header, tx_data and tx_size which
represent TX i.e. request while RX is represented by rx_data and rx_size
with reply's header equivalent missing.
Reply header may contain some vital information including, but not
limited to, received payload size. Some IPCs have entire payload found
within RX header instead. Content and value of said header is context
dependent and may vary between firmware versions and target platform.
Current model does not allow such IPCs to function at all.
Rather than appending yet another parameter to an already long list of
such for sst_ipc_tx_message_XXXs, declare message container in form of
struct sst_ipc_message and add them to parent's ipc_message declaration.
Align haswell, baytrail and skylake with updated request-reply model and
modify their reply processing functions to save RX header within message
container. Despite the range of changes, status quo is achieved.
ASoC: soc-core: tidyup for snd_soc_dapm_new_controls()
snd_soc_dapm_new_controls() registers controls by using
for(... i < num; ...). It means if widget was NULL, num should be zero.
Thus, we don't need to check about widget pointer.
This patch also cares missing return value.
