phy: mtk-mipi-csi: add driver for CSI phy

This is a new driver that supports the MIPI CSI CD-PHY version 0.5

The number of PHYs depend on the SoC.
Each PHY can support D-PHY only or CD-PHY configuration.
The driver supports only D-PHY mode, so CD-PHY
compatible PHY are configured in D-PHY mode.

[Julien Stephan: simplify driver model: one instance per phy vs
one instance for all phys]

phy: phy-mtk-dp: Add driver for DP phy

This is a new driver that supports the integrated DisplayPort phy for
mediatek SoCs, especially the mt8195. The phy is integrated into the
DisplayPort controller and will be created by the mtk-dp driver. This
driver expects a struct regmap to be able to work on the same registers
as the DisplayPort controller. It sets the device data to be the struct
phy so that the DisplayPort controller can easily work with it.

The driver does not have any devicetree bindings because the datasheet
does not list the controller and the phy as distinct units.

The interaction with the controller can be covered by the configure
callback of the phy framework and its displayport parameters.

phy: mediatek: Move mtk_mipi_dsi_phy driver into drivers/phy/mediatek folder

more suitable to place a phy driver into phy driver folder, so move
mtk_mipi_dsi_phy driver into phy driver folder.

phy: phy-mt65xx-usb3: add mediatek directory and rename file

The driver is actually for T-PHY which supports USB3.0, PCIe and SATA,
and supports more SoCs now, but not just only for series of mt65xx SoCs,
so the name of file, data struct, functions etc with 'mt65xx' may cause
misunderstanding when new SoCs are supported. Here rename them to reflect
the real functions and also enhance readability.

And also update MAINTAINERS file to reflect the correct driver
