cubieboard2: Accommodate U-Boot environment on SD-card
According to current "include/configs/sunxi-common.h"
U-Boot environment is stored on SD-card with offset 544 kB
and its size is limited as 128 kB.
Given memory layout of sunxi boards:
1. SPL
2. U-Boot
3. U-Boot environment
4. Partitions
(see http://linux-sunxi.org/Bootable_SD_card#SD_Card_Layout for details)
we need to make sure the first real partition starts at least
with 544+128 kB offset. Adding a small safety gap let's put
the first partition with offset 1MB from the beginning of SD-card.
Otherwise current setup gets broken as soon as one saves U-Boot
environment with "saveenv" which basically overwrites FAT partition with
zImage and board no longer boots into Linux kernel.
[Peter: extend description, add padding to u-boot partition instead]
