[PATCH v2 5/7] ARM: socfpga: add Enclustra AA1 demo env files

[Lothar Rubusch <l.rubusch@gmail.com>]

Provide additional uboot.env text environment files meant as a generic
demo. The default environment uses a uboot.env. The default environment
works somehow. This environment provides better support but only shows
one possible approach used in the Enclustra reference design setups.
