Convert the mfd: mediatek: mt6397 binding to DT schema format.

MT6323, MT6358, and MT6397 are PMIC devices with multiple function
subdevices. They share a common PMIC design but have variations in
subdevice combinations.

Key updates in this conversion:

1. RTC:
   - Convert rtc-mt6397.txt and merge into parent MT6397 PMIC DT schema.

2. Regulators:
   - Align to generic name "regulators".
   - Update references from .txt to .yaml for mt6323, mt6358, and mt6397
     regulators.
   - Simplify regulator name labels in device tree examples.

3. Audio Codec:
   - Convert sound/mt6358.txt and merge into parent MT6397 PMIC DT schema.
   - Align to generic name "audio-codec" for codec and sound subdevices.
   - Add "mediatek,dmic-mode" and "Avdd-supply" properties.

4. Clocks:
   - Align to generic name "clocks" for clockbuffer subdevices.

5. LEDs:
   - Convert leds-mt6323.txt and merge into parent MT6397 PMIC DT schema.
   - Update LED binding.

6. Keys:
   - Add detailed descriptions for power and home keys.
   - Add compatible: mediatek,mt6358-keys.

7. Power Controller:
   - Convert mt6323-poweroff.txt and merge into parent MT6397 PMIC DT
     schema.
   - Add #power-domain-cells property to fix dt-binding check error.
   - Clarify "BBPU" as "Baseband power up".

8. Pinctrl:
   - Align to generic name "pinctrl" instead of "pin-controller".

9. Compatible:
   - Drop "mediatek,mt6357" since there is a separated DT Schema
     for PMIC MT6357.

Additional updates:
- MAINTAINERS: Add co-maintainers and reference to
  mfd/mediatek,mt6397.yaml for LED and power-controller drivers.
- input/mediatek,pmic-keys.yaml: Update reference to
  mfd/mediatek,mt6397.yaml.

Changes for v1:
 - This patch depends on conversion of mediatek,mt6397-regulator.yaml
   [1] https://lore.kernel.org/lkml/20240807091738.18387-1-macpaul.lin@mediatek.com/T/

Changes for v2:
 - This patch has been made base on linux-next/master git repo.
 - Keep the parent and child relationship with mediatek,pwrap in description.
   [2] https://lore.kernel.org/all/20240826-slurp-earphone-0d5173923ae8@spud/
 - Keep the $ref for regulators since dt_binding_check didn't report any issue
   based on linux-next/master repo.
 - Fix description of mt6397/mt6323 devices, use "power management chip"
   instead of "multifunction device"
 - Drop unnecessary comments or description according to the review.
 - Convert sub-modules to DT Schema:
  - RTC, LEDs, power-controllers, regulators
 - Drop duplicate sub node name and description for sub-modules
  - RTC, Keys
 - examples:
  - drop parent pwrap node
  - Add examples from mediatek,mt6323-regulator.yaml
  - Add examples from mediatek,mt6358-regulator.yaml
  - Add examples from mediatek,mt6397-regulator.yaml
  - Complete the examples as could as possible.

Changes for v3:
 - Rebased on linux-next/master git repo near next-20240906.
 - Revise commit message.
 - Regulators:
  - Use "additionalProperties: true" and add "contains" for matching
    $ref DT bindings.
  - Simplify regulator name labels in device tree examples.
 - LEDs:
  - Use LED bindings.
 - Squash following patches in v2 for removing old text format DT bindings
   into this patch, includes:
  - leds-mt6323.txt, mt6323-poweroff.txt, rtc-mt6397.txt, sound/mt6358.txt.
 - Fix file format of DT schemas, add blank between properties.
 - Fix 'make checkrefdoc' errors, update reference in mediatek,pmic-keys.yaml.

Changes for v4:
 - Remove "mediatek,mt6357" from PMIC's compatible string since there is a
   seperated DT schema for PMIC mt6357.

+  - RTC
+  - Audio codec
+  - GPIO
+  - Clock
+  - LED
+  - Keys
+  - Power controller
+
+  It is interfaced to host controller using SPI interface by a proprietary hardware
+  called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap.
+  See the following for pwrap node definitions:
