Some skl sst context are not dependent of platform and initializing them
independently for each platform can lead to errors. So optimize by
moving them to a helper function and platform specific init code can
call this.

If D3 IPC fails or times out, firmware needs to be reloaded as driver
continues the reset.
So set the fw_load flag to false to reload the firmware in D0.

In system suspend, firmware needs to be re-downloaded as IMR is cleared.
When firmware is downloaded in D0, core state is not set to running
state causing instability with subsequent D0-D3 cycles.

So set the core state correctly during D0 and check the DSP core state
if not in reset to set the DSP to D3.

During S3->S0 transition, sometime ROM init fails because of
authentication engine loads later than the OS. In this case driver
waits for a longer period and then retries the FW download causing
huge delay in resume time of audio device.

To avoid this, ROM INIT wait time is set to a optimal value and
increased the retries for firmware download.

to driver infrastructure to support multiple core.

A new object skl_dsp_cores is introduced to support multiple
core. Helpers skl_dsp_get_core() skl_dsp_put_core() help to
managed the cores.

differences like no Code Load DMA and uses HDA DMA for code
loading, DSP D0 and D3 sequences are different.

These changes are comprehended by adding different DSP power up
