Add support for DH electronics i.MX8M Plus DHCOM SoM on PDK3 carrier board.
Currently supported are serial console, EQoS and FEC ethernets, eMMC, SD,
SPI NOR, CAN, M.2 E-Key or M.2 M-Key PCIe, USB .

V2: - Rename clk-xtal25 node name to clock-xtal25
- Rename i2cmux@ to i2c-mux@
- Rename clk@6b node to clock@6b
- Drop so far unused clock-codec
- Drop status = "okay" from typec@3d and ethernet-phy@7 nodes
V3: - Switch PCIe to fixed-clock source until Si521xx driver lands,
this is OK since the Si521xx is always on anyway and the I2C
interface is only used to tune it if necessary, which it is
not on this board.
