[v2,12/18] media: venus: Refactor struct hfi_session_get_property_pkt
Commit Message
The struct hfi_session_get_property_pkt is always used to fectch a
single property. Make that explicit in the code and avoid a single
element array at the end of the struct.
This change fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:194:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

The conversion of `data[1]` to plain `data` is fine but, the conversion
of `num_properties` to `one` doesn't fit the naming convention of this
code which uses `num_something` extensively.
Please retain the name `num_properties` for that reason.
Then add.
