mvebu: cortex-a72: enable U-Boot NVMEM driver

In order to not have to ship envtools configuration per board, we can
instead rely on the kernel U-Boot environment NVMEM driver through which
envtools can read/write the environement.

Since size difference is negligeble and this subtarget has rather large
storage regardless, enable it by default.
