media: i2c: adv748x: Use devm to allocate the device struct
Switch to devm_kzalloc() when allocating the adv748x device struct.
The sizeof() is updated to determine the correct allocation size from
the dereferenced pointer type rather than hardcoding the struct type.
[Kieran: Change sizeof() to dereference the pointer type]
