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: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

phy: mediatek: remove temporary variable @mask_ Remove the temporary @mask_, this may cause build warning when use clang compiler for powerpc, but can't reproduce it when compile for arm64. the build warning is caused by: "warning: result of comparison of constant 18446744073709551615 with expression of type (aka 'unsigned long') is always false [-Wtautological-constant-out-of-range-compare]" More information provided in below lore link. After removing @mask_, there is a "CHECK:MACRO_ARG_REUSE" when run checkpatch.pl, but due to @mask is constant, no reuse problem will happen.
