Subject: [PATCH v2 06/10] media: hantro: Use capture buffer width and height
 for H264 decoding

Calculations for motion vector buffer offset is based on width and height
from the configured capture format, lets use the same values for macroblock
width and height hw regs.

Fixes: dea0a82f3d22 ("media: hantro: Add support for H264 decoding on G1")

Changes in v2:
  - new patch split from "media: hantro: Fix H264 motion vector buffer offset"
