ASoC: Intel: avs: Fixes and new boards support

Merge series from Cezary Rojewski <[e-mail]>:

Two fixes are leading the way - one addresses the incorrect DMA mask
assignment (typo) at driver probe. The other, fixes a potential buffer
overflow when copying data received from firmware to kernel buffer.
However unlikely, the fix should still be there.

Then a range of patches providing the support for:
- AML with rt286 (machine board)
- KBL-R for rt298 (codec)
- KBL-R with rt298 (machine board)
- APL/KBL with da7219 (machine board)
- Addition of all the missing SKL-based PCI ids to core.c

Of the remaining changes, only one stands out - special case is provided
for "unsupported" IPCs. The driver supports a range of platforms,
however, on some generations given IPC may not be supported. Such call
shall not be treated as "invalid" - those are two different scenarios.

Everything else in the patchset is mostly a readability improvement:
spelling fixes and log messages issues, code simplification.
