Add support for PHY type switch via the mediatek topmisc syscon.
This is needed on mt7981 to make the PCIe correctly work and display
LinkUp.
Follow the same implementation done on Linux kernel with the usage of
the mediatek,syscon-type property.
Example:
u3port0: usb-phy@11e10700 {
reg = <0x11e10700 0x900>;
clocks = <&topckgen CK_TOP_USB3_PHY_SEL>;
clock-names = "ref";
#phy-cells = <1>;
mediatek,syscon-type = <&topmisc 0x218 0>;
status = "okay";
};

As part of bringing the master branch back in to next, we need to allow

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

The T-PHY controller is designed to use use PLL integer mode, but
in fact use fractional mode for some ones on mt8195 by mistake,
this causes signal degradation (e.g. eye diagram test fail), fix
it by switching PLL to 26Mhz from default 48Mhz to improve signal
quality.

Prefer to make use of FIELD_PREP() macro to prepare bitfield value,
then no need local macros anymore.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

The driver provides PHY for USB2, USB3.0, PCIe and SATA, and now
we just enable PCIe. As for the other functionalities will be
added gradually in upcoming days.
This is adapted from the Linux version.
