Subject: [PATCH v4 08/25] media: iris: Fix missing function pointer
 initialization

The function pointers responsible for setting firmware properties were
never initialized in the instance capability structure, causing it to
remain NULL. As a result, the firmware properties were not being set
correctly.

Fix this by properly assigning the function pointers from the core
capability to the instance capability, ensuring that the properties are
correctly applied to the firmware.
