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
