Subject: [PATCH v2 16/18] media: venus: Refactor hfi_sys_get_property_pkt

This struct was only used to get the version from the core. Make that
explicit.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:77:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
