In preparation to adding fully virtualized planes, move struct
dpu_hw_pipe instance from struct dpu_plane to struct dpu_plane_state, as
it will become a part of state (allocated during atomic check) rather
than part of a plane (allocated during boot).

now that pipe_hw has been made part of the dpu_plane_state, it means
that it can also change with atomic state.

In this change, I can see you update this only in dpu_plane_reset() 
which will be invoked during the drm_mode_config_reset().

Should this pipe_hw assignment be moved to the dpu_plane_atomic_update() 
function?

dpu_plane_atomic_update() is too late for the assignment.  Probably you 
meane dpu_plane_atomic_check(). However in this change I didn't want to 
change the logic of the code. Previously pipe_hw was available at all 
the times. With this change I also want to make it available at all the 
times, which means resetting it in the _reset() function. It will be 
moved to atomic_check() later, in the virtual planes series.

Probably I should do two changes for the v2:
- Use inline helper insted of hardcoding kms->rm.sspp_blks[pipe - 
SSPP_NONE] everywhere
- Add the text above as a comment to the assignment in the _reset() 
function.

Yes, my first concern was that dpu_plane_reset() is to reset the state 
so using it to assign the pipe_hw seemed a little strange to me in terms 
of location.

So I think leaving a comment that after virtual planes, this location 
will be changed will make it more clear.

Thanks
