[PATCH v2 0/3] board: sophgo: milkv_duo: Add ethernet support for Milk-V Duo board

[Kongyang Liu <seashell11234455@gmail.com>]

This series add init code for cv1800b ethernet phy and enable ethernet
support for Sophgo Milk-V Duo board.

In cv1800b, as the PHY register phy_id being initialized to 0, it is
necessary to initialize the PHY before the ethernet driver initialization.
Therefore, the initialization code is placed in the board_init function.

For the Linux kernel, due to the presence of a hibernation mechanism, whether
the phy id will be reset to 0 after hibernation and how to reassign it
thereafter remains an issue to consider. Once this issue is resolved, the
Ethernet driver for the Milk-V Duo will be sent to the kernel.

Changes in v2:
- Change compatible
- Add clocks and interrupt properties.
