Add basic support for pcb8290. It has 2 lan8814 phys(each phy is a
quad-port) on the external MDIO bus and no SFP ports.
Signed-off-by: Horatiu Vultur <horatiu.vultur@xxxxxxxxxxxxx>
---
v2->v3:
- update coma-mode-gpios, set them to OPEN_DRAIN
v1->v2:
- add comments for pps_out_pins and ptp_ext_pins pins
- fix commit message.
