phy: add driver for MediaTek XFI T-PHY

Add driver for MediaTek's XFI T-PHY which can be found in the MT7988
SoC. The XFI T-PHY is a 10 Gigabit/s Ethernet SerDes PHY with muxes on
the internal side to be used with either USXGMII PCS or LynxI PCS,
depending on the selected PHY interface mode.

The PHY can operates only in PHY_MODE_ETHERNET, the submode is one of
PHY_INTERFACE_MODE_* corresponding to the supported modes:

* USXGMII \
* 10GBase-R }- USXGMII PCS - XGDM \
* 5GBase-R / \
}- Ethernet MAC
* 2500Base-X \ /
* 1000Base-X }- LynxI PCS - GDM /
* Cisco SGMII (MAC side) /

I chose the name XFI T-PHY because names of functions dealing with the
phy in the vendor driver are prefixed "xfi_pextp_".

The register space used by the phy is called "pextp" in the vendor
sources, which could be read as "_P_CI _ex_press _T_-_P_hy", and that
is quite misleading as this phy isn't used for anything related to
PCIe, so I wanted to find a better name.

XFI is still somehow related (as in: you would find the relevant
places using grep in the vendor driver when looking for that) and the
term seemed to at least somehow be aligned with the function of that
phy: Dealing with (up to) 10 Gbit/s Ethernet serialized differential
signals.

In order to work-around a performance issue present on the first of
two XFI T-PHYs found in MT7988, special tuning is applied which can
be selected by adding the 'mediatek,usxgmii-performance-errata'
property to the device tree node, similar to how the vendor driver is
doing that too.

There is no documentation for most registers used for the
analog/tuning part, however, most of the registers have been partially
reverse-engineered from MediaTek's SDK implementation (see links, an
opaque sequence of 32-bit register writes) and descriptions for all
relevant digital registers and bits such as resets and muxes have been
supplied by MediaTek.

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.

This is similar to the hdmi driver I fixed earlier, and I guess the
common-clk bug would sooner or later also manifest here, so just use
the exact same solution I chose for the other driver, and hope that
any future drivers just copy it from here.
