- Implement upstream specific memory_alloc/map and
memory_unmap/free API based on standard dma_alloc_attr()
and dma_free_attr() APIs which allocates and map dma buffer.
- Combine alloc and map, unmap and free.

Re-structure the memory_ops code so that
upstream driver use mem_ops defined on
msm_vidc_memory.c and downstream driver
use mem_ops defined on msm_vidc_memory_ext.c.
It helps to modularize the code even further.

Only keep minimal entries in dtsi, which is essential for
other drivers usage. Move remaining all data into platform
resource file.
Remove device_tree dependency and maintain platform_data
to initialize resources like regulators, interconnects,
clocks, reset_clocks, subcaches and context_banks.
Read static data like freq_table, firmware_name, pas_id
also from platform_data instead of from dtsi.

When client queued a buffer, v4l2 framework
compares the client Dmabuf with the existing
dmabuf in the bufs array at the same index.
If the dmabuf is different then v4l2 framework
would call unmap_dmabuf, detach_dmabuf callbacks
for the old buffer and then calls attach_dmabuf,
map_dmabuf callbacks for the new buffer before
qbuf callback is made to driver. If the dmabuf
is same then qbuf callback will be made directly.
V4l2 framework expects that clients recycles the
same buffers in the same indices so that when
v4l2 framework compares dmabuf it won't unmap
or map buffers.
If client recycle the buffers in different indices
still usecase works but there will be unnecessary
unmap, map overhead will be incurred.
If client does not recycle the buffers at all,
meaning every time client queues new buffers
then special handling is required for decoder
output buffers which are used for reference by
video hardware.If any buffers are used by video
hardware as reference buffers then firmware returns
those buffers with READ_ONLY flag and they are kept
in read_only list and when read_only grows beyond
some limit then driver would ask firmware to release
those READ_ONLY buffers and when firmware responds
driver would delete these READ_ONLY buffers.

[1] Remove CAP_FLAG_ROOT flag. Root willbe identified
with has_parents() api.
[2] Replace field(struct msm_vidc_inst_cap) cap -> cap_id.
[3] Rename below pool apis.
msm_memory_alloc -> msm_memory_pool_alloc
msm_memory_free -> msm_memory_pool_free
[4] Remove struct msm_vidc_inst_cap_entry usage in inst.
inst->firmware.list -> inst->firmware_list
inst->children.list -> inst->children_list
[5] Organize msm_vidc_inst_capability_type enums in such
a way that all parents placed first then children. It
will save CPU cycles while preparing caps_list.

Track dmabuf refcount during dma_buf_get() and dma_buf_put().
So if any dmabuf present with non-zero refcount during close,
then i.e a dmabuf leak. So during session close print error
and call dma_buf_put_refcount_completely() api to recursively
reduce the count to zero and will call dma_buf_put() to avoid
dmabuf leak from video driver side.

- add support to skip lazy unmapping for decoder
output buffers only. Map twice for these buffers.
- v4l2 client owned RO SMMU mapped buffers are
maintained separately in read_only list.
- For FBD with RO flag from fw, add buffer to read_only
list. Else remove from this list.
- During FTB, if buffer present in read_only list,
add RO flag to hfi buffer and queue to fw.
- During streamoff output, unmap all buffers except
those present in read_only list.
- During close, unmap completely and clean up read_only
list, output list.
