rockchip: rk3288-tinker: Fix slow Ethernet initializion
For some reason the Ethernet PHY reset delay is set to 1 second, this
cause an unneccecery long boot delay.
Tinker Board use RTL8211E or RTL8211F 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.
Before:
1,404,971 960,924 eth_common_init
2,438,830 1,033,859 eth_initialize
2,444,449 5,619 main_loop
2,445,153 704 cli_loop
After:
1,404,987 960,710 eth_common_init
1,519,110 114,123 eth_initialize
1,524,734 5,624 main_loop
1,525,452 718 cli_loop
