[PATCH 1/3] riscv: dts: spacemit: Add USB2 PHY node for K1

[Ze Huang <huang.ze@linux.dev>]

K1's DWC3 USB 3.0 controller requires two separate PHYs to function:
the USB 3.0 combophy (for SuperSpeed) and a USB 2.0 PHY (for High-Speed,
Full-Speed, etc.).

Add node for this second USB 2.0 PHY (usbphy2).
