Add an EMAC driver for the CH32V307's Synopsys DesignWare Ethernet MAC, supporting both the built-in 10M PHY and external PHYs via RMII/MII. The driver implements embassy_net_driver::Driver with DMA descriptor rings (chained mode), SMI/MDIO PHY management, and async TX/RX via interrupt-driven wakeups. For the built-in 10M PHY (PhyInterface::Internal10M): - Configures PLL3 to 60MHz as the PHY clock source - Enables the PHY via EXTEND.CTR.ETH_10M_EN - Sets MACCR.IRE for 50-ohm impedance matching - Writes PHY_MDIX register (0x1E) for auto PN polarity detection - Enables promiscuous mode for PHY polarity detection Includes a TCP echo server example (examples/ch32v307/src/bin/eth.rs) that initializes the 10M PHY, obtains an IP via DHCP, and echoes TCP data on port 1234. Tested on hardware with ping and TCP. Depends on EMAC register definitions from ArthurHeymans/ch32-data, generated into ArthurHeymans/ch32-metapac (rev b079130). The ch32-metapac dependency is temporarily pointed at this fork until the register definitions are upstreamed to ch32-rs/ch32-data.

Add an EMAC driver for the CH32V307's Synopsys DesignWare Ethernet MAC,
supporting both the built-in 10M PHY and external PHYs via RMII/MII.
The driver implements embassy_net_driver::Driver with DMA descriptor
rings (chained mode), SMI/MDIO PHY management, and async TX/RX via
interrupt-driven wakeups.
For the built-in 10M PHY (PhyInterface::Internal10M):
Includes a TCP echo server example (examples/ch32v307/src/bin/eth.rs)
that initializes the 10M PHY, obtains an IP via DHCP, and echoes TCP
data on port 1234. Tested on hardware with ping and TCP.
Depends on EMAC register definitions from ArthurHeymans/ch32-data,
generated into ArthurHeymans/ch32-metapac (rev b079130). The
ch32-metapac dependency is temporarily pointed at this fork until the
register definitions are upstreamed to ch32-rs/ch32-data.
ch32-rs/ch32-data#27 is the PR for the ch32-data update.
