As talked about in commit 14d3ae2efeed ("ARM: 8507/1: dma-mapping: Use
DMA_ATTR_ALLOC_SINGLE_PAGES hint to optimize alloc"), it doesn't
really make sense to try to allocate contiguous chunks of memory for
video encoding/decoding. Let's switch the Mediatek vcodec driver to
pass DMA_ATTR_ALLOC_SINGLE_PAGES and take some of the stress off the
memory subsystem.

In mtk_vcodec_mem_free(), there are two cases where a NULL VA is passed:
- mem->size == 0: we are called to free no memory. This may happen when
we call mtk_vcodec_mem_free() twice or the memory has never been
allocated.
- mem->size > 0: we are called to free memory but without VA. This means
that we failed to free the memory for real.
Both cases are not expected to happen, and we want to have clearer error
messages to describe which one we just encountered.
Update the error messages to include more information for that purpose.

In mtk_vcodec_mem_alloc() and mtk_vcodec_mem_free(), the value of
mem->size is not expected to change before and when using the DMA APIs
and debug print, so there's no point in keeping local copies of it.
Drop the local variable "size" in the mentioned functions, and update
printk format identifiers accordingly.
This makes the code slightly more visually consistent, and retrieve a
small amount of memory that is used for no real purpose.

mtk_v4l2_err() already uses dev_err(), so don't print the device name
again. Print the function name instead.

Need to use encoder device to allocate/free encoder memory when calling
mtk_vcodec_mem_alloc/mtk_vcodec_mem_free, or leading to below crash log
when test encoder with decoder device.
