Add automatic boot counter that increases after every reset. After a power-on reset, it will be initialized with 1, and each reboot will increment the value by 1. By default it is disabled if bootlimit isn't set.

GPT Partition labels are used for determining the right root filesystem to boot from.
The U-Boot environment is configured to reside in the eMMC hardware boot partition we are currently booted from.
This should enable a dual copy approach for upgrading the bootloader. One can overwrite the inactive hardware partition with new bootloader and environment and afterwards switch the eMMC boot partition for an atomic bootloader switch.

Currently, only the first MAC address is read from the fuses.
The second MAC address is not read and Linux assigns a random one.
To prevent this behavior, read the second MAC address from the fuses and store it into the eth1addr environment variable so that it can be passed to Linux.
