apm821xx: meraki-mx60: fix ubootenv definitions

Needed to avoid probe errors.

There are two partitions from 0-20000 and 80000-100000.

This is redundant-count and not regular u-boot,env

Add status = "disabled" as the u-boot env driver can't handle redundant
environments properly. As a result, fw_printenv ends up not working
right.
