media: renesas: vsp1: Fix code checks in frame size enumeration

The media bus code passed to the .enum_frame_size() operation for the
sink pad is required to be supported by the device, but not to match the
current format. All entities that use the vsp1_subdev_enum_frame_size()
helper, as well as the SRU and UDS entities that implement the operation
manually, perform the check incorrectly.

Fix the issue by implementing the correct code check in the
vsp1_subdev_enum_frame_size(). For the SRU and UDS, to avoid duplicating
code, use the vsp1_subdev_enum_frame_size() as a base and override the
enumerated size on the source pad with entity-specific constraints.

While at it, include the missing <linux/mutex.h> as the code locks
mutexes.
