media: venus: helpers: Fix ALIGN() of non power of two

ALIGN() expects its second argument to be a power of 2, otherwise
incorrect results are produced for some inputs. The output can be
both larger or smaller than what is expected.

For example, ALIGN(304, 192) equals 320 instead of 384, and
ALIGN(65, 192) equals 256 instead of 192.

However, nestling two ALIGN() as is done in this case seem to only
produce results equal to or bigger than the expected result if ALIGN()
had handled non powers of two, and that in turn results in framesizes
that are either the correct size or too large.

Fortunately, since 192 * 4 / 3 equals 256, it turns out that one ALIGN()
is sufficient.

media: venus: Fix NV12 decoder buffer discovery on HFI_VERSION_1XX

HFI_VERSION_1XX uses HFI_BUFFER_OUTPUT not HFI_BUFFER_OUTPUT2 for decoder
buffers.

venus_helper_check_format() places a constraint on an output buffer to be
of type HFI_BUFFER_OUTPUT2. HFI_1XX uses HFI_BUFFER_OUTPUT though.

Switching to the logic used in venus_helper_get_out_fmts() first checking
for HFI_BUFFER_OUTPUT and then HFI_BUFFER_OUTPUT2 resolves on HFI_1XX.

media: venus: do not queue internal buffers from previous sequence

During reconfig (DRC) event from firmware, it is not guaranteed that
all the DPB(internal) buffers would be released by the firmware. Some
buffers might be released gradually while processing frames from the
new sequence. These buffers now stay idle in the dpblist.
In subsequent call to queue the DPBs to firmware, these idle buffers
should not be queued. The fix identifies those buffers and free them.

media: venus: vdec: decoded picture buffer handling during reconfig sequence

In existing implementation, driver is freeing and un-mapping all the
decoded picture buffers(DPB) as part of dynamic resolution change(DRC)
handling. As a result, when firmware try to access the DPB buffer, from
previous sequence, SMMU context fault is seen due to the buffer being
already unmapped.

With this change, driver defines ownership of each DPB buffer. If a buffer
is owned by firmware, driver would skip from un-mapping the same.
