DaVinci: correct MDSTAT.STATE mask
MDSTAT.STATE occupies bits 0..5 according to all available documentation, so fix
the mask which previously was leaving out the intermediate state indicator bit.
While at it, introduce two #define's for that mask -- unfortunately, we can't
use a single #define as the assembly code can't include <asm/arch/hardware.h>
due to C-specfic constructs in it.
