Subject: [PATCH v2 0/4] qrb2210-rb1: HDMI/I2S audio playback support

This series adds a feature to playback/output audio via HDMI
on the Qualcomm RB1 board. Since RB1 and RB2 are very similar
to each and other and most likely use the same mainboard therefore
this series is pretty much a rework of the similar patchset for RB2.

Changes since v1:
- added tags;
- patch that adds sndcard compatble is moved into separate series
and also one new patch is added there;
here: https://lore.kernel.org/linux-sound/20251007-qrb2210-qcm2290-sndcard-v1-0-8222141bca79@linaro.org/
- resorted cpu,codec,platform subnodes of HDMI DAI link
(as asked by Konrad);
- apt => APR in "arm64: dts: qcom: qcm2290: add apr and its services"
(as suggested by Dmitry);
- resorted pins in LPASS TLMM node (as asked by Konrad);
