The VDEC_HW_ACTIVE bit is located at offset 0, bit 4 of the VDECSYS iospace. Only the mask was previously defined, with the address being implicit. Explicitly define the address, and append a '_MASK' suffix to the mask, to make accesses to this bit clearer. This commit brings no functional change. Signed-off-by: Nícolas F. R. A.
