Add support for MFCv12, with a new register file and
necessary hw control, decoder, encoder and structural changes.
Add luma dbp, chroma dpb and mv sizes for each codec as per the
UM for MFCv12, along with appropriate alignment.

Anyway if you have lcu_width, lcu_height, please use it.
Or maybe better drop them and use:
width64 = ALIGN(ctx->img_width, 64);
height32 = ALIGN(ctx->img_height, 32);
which seems to fit better here, I suppose it could replace all ALIGN(ctx->img_...).

+ (((MB_HEIGHT(y)+1)/2)*2) * 64 + 1024)
(MB_HEIGHT(y)+1)/2)*2) == ALIGN(MB_HEIGHT(y), 2)
You could replace all S5P_MFC_DEC_MV_SIZE_V* with:
#define S5P_MFC_DEC_MV_SIZE(x, y, offset).
