Subject: adding saveenv-command for bananapi r2
bananapi r2 can be booted from sd-card and emmc
saving the environment have to choose the storage
from which the device has booted
also the offset is set to 1MB-50Kb to make sure env is written
to block "user data area" between uboot and first partition

v3: removed changes in defconfig (users choice)
v2: fixed bracket-style in if-else statement
