this patch improve vpif_buffer_prepare() callback, as buf_prepare()
callback is never called with invalid state and check for
vb2_plane_vaddr(vb, 0) is dropped as payload check should
be done unconditionally.

This patch is needed in preparation to add MFC V8
where the register offsets are changed w.r.t MFC V6/V7.
This patch adds variants of MFC V6 and V7 while
accessing MFC registers. Registers are kept in mfc context
and are initialized to a particular MFC variant during probe,
which is used instead of macros.
This avoids duplication of the code for MFC variants
V6 & V7, and reduces the if_else checks while accessing
registers of different MFC variants.

Currently, for formats that are not H264, MFC driver will check
the consumed stream size returned by the firmware and, based on that,
will try to decide whether the bitstream buffer contained more than
one frame. If the size of the buffer is larger than the consumed
stream, it assumes that there are more frames in the buffer and that the
buffer should be resubmitted for decode. This rarely works though and
actually introduces problems, because:
- v7 firmware will always return consumed stream size equal to whatever
the driver passed to it when running decode (which is the size of the whole
buffer), which means we will never try to resubmit, because the firmware
will always tell us that it consumed all the data we passed to it;
- v6 firmware will return the number of consumed bytes, but will not
include the padding ("stuffing") bytes that are allowed after the frame
in VP8. Since there is no way of figuring out how many of those bytes
follow the frame without getting the frame size from IVF headers (or
somewhere else, but not from the stream itself), the driver tries to guess that
padding size is not larger than 4 bytes, which is not always true;
The only way to make it work is to queue only one frame per buffer from
userspace and the check in the kernel is useless and wrong for VP8.
So adding VP8 also along with H264 to disallow re-submitting of buffer
back to hardware for decode.

Currently, we allocate private codec buffers on STREAMON, which may fail
if we are out of memory. We don't check for failure though, which will
make us crash with the codec accessing random memory.
We shouldn't be failing STREAMON with out of memory errors though. So move
the allocation of private codec buffers to REQBUFS for OUTPUT queue. Also,
move MFC instance opening and closing to REQBUFS as well, as it's tied to
allocation and deallocation of private codec buffers.

- Honor return values from vb2_reqbufs on REQBUFS(0).
- Do not set the number of allocated buffers to 0 if userspace tries
to request buffers again without freeing them.
- There is no need to verify correct instance state on reqbufs, as we will
verify this in queue_setup().
- There is also no need to verify that vb2_reqbufs() was able to allocate enough
buffers (pb_count) and call buf_init on that many buffers (i.e. dst_buf_count
is at least pb_count), because this will be verified by second queue_setup()
call as well and vb2_reqbufs() will fail otherwise.
- Only verify state is MFCINST_INIT when allocating, not when freeing.
- Refactor and simplify code.

Timestamps for destination buffers are assigned by copying them from
corresponding source buffers when the decode operation results in a frame
being outputted to a destination buffer. But the decision when to do this, i.e.
whether the decode operation on current source buffer produced a destination
frame, is wrongly based on "display status". Display status reflects the status
of the destination buffer, not source.
This used to work for firmwares version <= 6, because in addition to the above,
we'd check the decoded frame type register, which was set to "skipped" if
a destination frame was not produced, exiting early from
s5p_mfc_handle_frame_new().
Firmware >=7 does not set the frame type register for frames that were not
decoded anymore though, which results in us wrongly overwriting timestamps of
previously decoded buffers (firmware reports the same destination buffer address
as previously decoded one if a frame wasn't decoded during current operation).
To do it properly, we should be basing our decision to copy the timestamp on the
status of the source buffer, i.e. "decode status". The decode status register
values are confusing, because in its case "display" means "a frame has been
outputted to a destination buffer". We should copy if "decode and display"
is returned in it. This also works on <= v6 firmware, which behaves in the same
way with regards to decode status register.
