For some reason the Ethernet PHY reset delay is set to 1 second, this cause an unneccecery long boot delay.
Firefly-RK3288 use RTL8211 Ethernet PHY, datasheet list an initial 10ms delay and then a 30-76ms delay before accessing registers.
Change to use 80ms delay instead of a full second to speed up Ethernet initializion in U-Boot.
Also enable PHY_REALTEK, DM_ETH_PHY and PHY_GIGE to improve Ethernet PHY support in U-Boot.
