[U-Boot] [PATCH] atngw100: Use virtual address in CONFIG_ENV_ADDR

Ever since the CFI driver was rewritten to use virtual addresses, thus
eliminating the whole point of the map_physmem() macro, ATNGW100 has
been broken like this:

U-Boot> saveenv
Saving Environment to Flash...
Error: start and/or end address not on sector boundary

So let's take a different approach and store the virtual address in
CONFIG_ENV_ADDR. I personally believe that's rubbish and will break
whenever we decide to change the virtual-to-physical mapping in any way,
but it looks like it's the direction in which u-boot is currently
moving, and it does fix the problem.
