[PATCH v3 0/3] Cleanup Mediatek pinctrl device tree binding

[Alexandre Mergnat <amergnat@baylibre.com>]

Deprecate properties which shall not exist, leaked upstream from downstream
kernels, there's no reason to use them. Here the deprecated properties and
the generic properties which will replace them:

- mediatek,drive-strength-adv => drive-strength-microamp
- mediatek,pull-up-adv        => bias-pull-up
- mediatek,pull-down-adv      => bias-pull-down

Another commit has been added in v3 to make it easier to merge. [2]

Thanks AngeloGioacchino Del Regno to reported it. [1]

Changes in v3:
- Port another commit which modify the pinctrl from this serie [2].
- Rebased to linusw/linux-pinctrl as requested by the maintainer [3].
- Link to v2: https://lore.kernel.org/r/20230327-cleanup-pinctrl-binding-v2-0-f21fbcc3016e@baylibre.com

Changes in v2:
- Change the bias-pull enum values to match with other Mediatek SoC.
  That allows to use MTK generic define and be compliant with the MTK
  common pinctrl driver.
- Link to v1: https://lore.kernel.org/r/20230327-cleanup-pinctrl-binding-v1-0-b695e32e4f2e@baylibre.com
