Revert "[E09][DTS] increase drive strength of gmac1 pins and temporarily limit speed"
This reverts commit ad0b43254a4b133aa6cb18827eb60ec1698efeb4 because, after fixing the power domain configuration, changing the drive strength of the RGMII of gmac1 is no longer needed.

[E09] fix RGMII delays
- remove max-speed on gmac1 because now it works also at 1Gbps
- set rgmii mode instead of rgmii-id for both ethernet ports
- set correct delay values
- remove internal delays which are no longer needed
The delay values have been obtained in kernel user space by issuing this command (e.g. for ETH1):
echo 1000 > /sys/devices/platform/fe010000.ethernet/phy_lb_scanThe kernel then outputs a rectangular map:

The "O" in it means that the coordinates of the point can be passed, and the blank spaces are failed. The best values are those at the center of the rectangle, which are also printed in the last line for convenience.

[E09] configure ethernet leds
Configure mode and polarity of ethernet LEDs considering that, in E09 RevA, there are two hardware bugs:
- Left LEDs (orange=1Gbps, green=100Mbps) are swapped
- Right LED (activity) is active low
