The sunxi-common.h configs header used to contain a lot of random Allwinner platform related constants, but over the years we moved a lot of those definitions out there. Clean up the file to remove outdated comments which are leftovers from the olden days. Also remove the definition of LOW_LEVEL_SRAM_STACK, which is actually used nowhere in the whole source tree. This also uses the opportunity to add some section comments that helps structuring the header file and improving readability. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
