When decoding a 10bits bitstreams HEVC driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.

version 3:
- Propagate hantro_reset_raw_fmt() error.
I hope I have correctly understood Ezekiel's thoughts
in the way I have implemented them.
version 2:
- Remove struct hantro_ctx *ctx variable in hantro_try_ctrl()
because it isn't used anymore.

While this match 1:1 with the review comment (chain EBUSY), it does not
conceptually solved the problem since we always modify ctx here, and then modify
it futher into hantro_reset_raw_fmt() before we actually check if the queue is
busy. The code needs to be reorganize to check first, and modify after. Its
quite likely that bit_depth should be a parameter to hantro_reset_raw_fmt() so
we don't spread out the logic.

I actually tested v3, not v1:
Tested with 8bit tiled / P010 linear, as that's what we have in GStreamer
upstream and it fixed the badly selected format issue. No fluster hack was used.
Fluster score was: 141 / 147
