media: hantro: Reduce H264 extra space for motion vectors
A decoded 8-bit 4:2:0 frame need memory for up to 448 bytes per
macroblock with additional 32 bytes on multi-core variants.
Memory layout is as follow:
+---------------------------+
| Y-plane 256 bytes x MBs |
+---------------------------+
| UV-plane 128 bytes x MBs |
+---------------------------+
| MV buffer 64 bytes x MBs |
+---------------------------+
| MC sync 32 bytes |
+---------------------------+
Reduce the extra space allocated now that motion vector buffer offset no
longer is based on the extra space.
Only allocate extra space for 64 bytes x MBs of motion vector buffer
and 32 bytes for multi-core sync.
