ASoC: SOF: Intel: add SKL/KBL hardware code loader

Browse source

This patch adds support for the SkyLake and KabyLake code loader on
top of the SOF IPC4.

The work was initially contributed in 2018 by Liam Girdwood and Zhu
Yingjiang, and abandoned due to firmware signature issues. With the
existing support of IPC v4, it's time to re-add this capability.

This patch uses the newly added FSR (Firmware State Register)
definitions for DSP state handling and targeting, ass well as new
state definition for SKL which indicates that the firmware has been
started (similar to FW_ENTERED on other platforms).
