[PATCH 1/3] media: i2c: ov5640: Drop manual fwnode_handle_put() via scope-based cleanup

[Biren Pandya]

Utilize the __free(fwnode_handle) scoped guard macro from <linux/cleanup.h> to automate the lifecycle management of the endpoint fwnode in ov5640_probe().

This eliminates the need for the manual fwnode_handle_put() call, preventing potential memory leaks in error paths and simplifying the probe routine.
