336d4615f8 dm: core: Create a new header file for 'compat' features
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.

235bad02e5 phy: mediatek: add MediaTek T-PHY support for PCIe
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.
