[PATCH v3 4/6] media: mediatek: vcodec: Define address for VDEC_HW_ACTIVE

[Nícolas F. R. A. Prado]

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.
