Add a generic PHY driver for the TI DS125DF111 Multi-Protocol Dual-Channel Retimer. The driver currently supports only 10G and 1G link speeds but it can easily extended to also cover other usecases. Since the available datasheet (https://www.ti.com/lit/gpn/DS125DF111) does not name the registers, the name for the macros were determined by their usage pattern. A PHY device is created for each of the two channels present on the retimer. This allows for independent configuration of the two channels. This capability is especially important on retimers which have more than 2 channels that can be, depending on the board design, connected in multiple different ways to the SerDes lanes.
