Adding a new driver for the MIPI CSI CD-PHY module v 0.5 embedded in
some Mediatek soc, such as the MT8365

This driver was adapted from https://patchwork.kernel.org/project/linux-mediatek/cover/20200708104023.3225-1-louis.kuo@mediatek.com/

v1 can be found here: https://lore.kernel.org/all/20230403071929.360911-1-jstephan@baylibre.com/

v2 can be found here: https://lore.kernel.org/all/20230515090551.1251389-1-jstephan@baylibre.com/

Changelog
Changes in v3:
Binding file:
	- rename compatible string
	  mediatek,phy-mipi-csi-0-5 -> mediatek,mt8365-csi-rx
	- rename binding file to be as compatible string
	- change property mediatek,is_cdphy -> mediatek,phy-type using an
	  enum value instead of boolean for scalability
	- remove status property from example nodes
	- rename example node name 'mipi_rx_csi0: mipi_rx_csi0@11c10000' ->
	  'csi0_rx: phy@11c10000'
	- put reg address in lower case

include/dt-bindings/phy/phy.h:
	- add PHY_TYPE_CDPHY definition

Driver:
	- rename compatible string
	- rename property mediatek,is_cdphy -> mediatek,phy-type
	- rename CSIx* macro to CSIX* (x -> X)
	- fix style issue on the driver data structure
	- update MODULE_DESCRIPTION as suggested by Angelo
	  and update the kconfig module description to match it
	- add dphy /cdphy eq tuning function to factor the code
	  and increase readability
	- fix typo __PHY_MTK__MIPI_CSI__C_0_5_RX_REG_H_ -->
	  __PHY_MTK_MIPI_CSI_V_0_5_RX_REG_H_
	- reword commit message to update my contributions
	- added missing copyright
	- added module name in Kconfig

Changes in v2:
	- fix all comments on bindings
	- move the binding chunk from driver to binding commit
	- fix dt_binding_check error (reported by DT_CHECKER_FLAGS)
	- use a more generic compatible string
	- add a new dt properties to simplify the driver
	  "mediatek,is_cdphy"
	- rename the driver and the corresponding file to include
	  version
	- drop of_match_ptr()
	- use devm_platform_ioremap_resource
	- use phy-mtk-io.h api instead of regmap
	- rework the driver to use dt nodes to declare PHY instead of an
	  array in the driver
	- remove useless define for unused registers
	- remove support for CSI0A/B because it cannot be tested, and it
	  simplifies the driver for a first review
	- edit commit message and bindings to be more descriptive about the
	  hardware
