Do not use 0 as address for memory because of the special meaning for
pointers (null pointer). Change the spl bss start address to the second
page.

The problem was discovered with a static array initialized with zero.
The compiler placed the array at address 0 and thereby a pointer to the
array was interpreted as null pointer.
Changes in v2:
- Rework commit message and replace address null by 0

I think this patch get lost because of the "Convert
CONFIG_SPL_BSS_START_ADDR to Kconfig" change.
