This patch enables the Firefly Station M2 board dts build and fixes hardware issues: (#434)

1. Fixes GMAC1 clock hierarchy and adds phy-supply for stable networking.
2. Corrects RGMII delays (tx=0x4f, rx=0x24) to fix packet loss/CRC errors.
3. Assigns VOP2 ESMART0 layer to the cursor to fix rendering issues.
