thermal: int340x: Fix attr.show callback prototype
Control Flow Integrity (CFI) instrumentation of the kernel noticed that
the caller, dev_attr_show(), and the callback, odvp_show(), did not have
matching function prototypes, which would cause a CFI exception to be
raised. Correct the prototype by using struct device_attribute instead
of struct kobj_attribute.
