[PATCH v3] media: mediatek: vcodec: support 36 bits physical address

[Yunfei Dong]

The physical address on the MT8188 platform is larger than 32 bits,
change the type from unsigned int to dma_addr_t to be able to access
the high bits of the address.

Hi Yunfei,

Since the v2 patch is now merged in mainline as-is, you need to make a patch
on top of that.

So just post a new patch that applies to the mainline.

Regards,
