This serie aim to add the following audio support for the Genio 350-evk:
- Playback
  - 2ch Headset Jack (Earphone)
  - 1ch Line-out Jack (Speaker)
  - 8ch HDMI Tx
- Capture
  - 1ch DMIC (On-board Digital Microphone)
  - 1ch AMIC (On-board Analogic Microphone)
  - 1ch Headset Jack (External Analogic Microphone)

Of course, HDMI playback need the MT8365 display patches [1] and a DTS
change documented in "mediatek,mt8365-mt6357.yaml".

The period size represents the size of the DMA descriptor. To ensure all
DMA descriptors start from a well-aligned address, the period size must
be divided by (sample size * maxburst), not just by maxburst.
This adjustment allows for computing a higher maxburst value, thereby
increasing the performance of the DMA transfer.
Previously, snd_pcm_lib_period_bytes() returned 0 because the runtime HW
parameters are computed after the hw_params() callbacks are used.
To address this, we now use params_*() functions to compute the period
size accurately. This change optimizes the DMA transfer performance by
ensuring proper alignment and efficient use of maxburst values.

Support multiple endpoints on TLV320AIC32x4 codec port when
used in of_graph context.

This patch allows to share the codec port between two CPU DAIs.

Example:

Custom STM32MP157C board uses TLV320AIC32x4 audio codec. This codec
is connected to two serial audio interfaces, which are configured
either as rx or tx.

>From AsoC point of view the topolgy is the following:
// 2 CPU DAIs (SAI2A/B), 1 Codec (TLV320AIC32x4)
Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0
Record:   CPU-B-DAI(slave) <- (master)CODEC-DAI/port0

In the DT two endpoints have to be associated to the codec port:
tlv320aic32x4_port: port {
    tlv320aic32x4_tx_endpoint: endpoint@0 {
            remote-endpoint = <&sai2a_endpoint>;
    };
    tlv320aic32x4_rx_endpoint: endpoint@1 {
            remote-endpoint = <&sai2b_endpoint>;
    };
};

However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.

The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.
