media: si470x-i2c: add missed operations in remove

BugLink: https://bugs.launchpad.net/bugs/1859712
[ Upstream commit 2df200ab234a86836a8879a05a8007d6b884eb14 ]

The driver misses calling v4l2_ctrl_handler_free and
v4l2_device_unregister in remove like what is done in probe failure.
Add the calls to fix it.
