[PATCH v3 1/3] media: i2c: ov5640: use scoped fwnode_handle endpoint cleanup

[Biren Pandya <birenpandya@gmail.com>]

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 manual fwnode_handle_put() calls.
Additionally, drop the redundant !endpoint check before
v4l2_fwnode_endpoint_parse(), as the parse function already handles
NULL endpoints safely.

Changes in v3:
- Resend as a complete series to fix broken threading.
- Moved changelogs here.

Changes in v2:
- Used scoped __free(fwnode_handle) macro (Laurent).
- Dropped redundant !endpoint check in ov5640 (Sakari).
