Subject: [PATCH v2 0/5] add sof support on imx95

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

Add sof support on imx95. This series also includes some changes to
the audio-graph-card2 binding required for the support.

---
Changes in v2:
- Added new binding for 95's CM7 core with SOF. fsl,dsp.yaml is no longer used.
- "hp-det-gpios" and "widgets" properties now reference the definitions from audio-graph.yaml
- Removed extra empty spaces from DTS as suggested by Frank
- Ordered 'edma2', 'sai3', 'wm8962' DT nodes alphabetically. The order of the nodes
placed inside / is kept the same for readability
- Ordered driver header files includes alphabetically as suggested by Frank
- Removed "reg-names" and changed the maximum size of the "reg" property to 1 to align
with the other NXP CPUs sharing the same programming model (i.e: audio processing with SOF).
The region described in the DTS is the SRAM and the mailbox region is now hardcoded in the
driver as an offset to the start of the SRAM region.
- Added new binding with properties required by all NXP CPUs sharing the same programming
model (i.e: audio processing with SOF).
- Various driver adjustments made to accomodate the DT changes + some bug fixing related
to the mboxes not being requested/free'd on resume/suspend.
- Fixed value passed to "dma-channel-mask". A set bit means the channel is masked, not the
other way around.
