ipa: rpi: Initialize enum controls with a list of values

This is how uvcvideo and rkisp1 do it. See ee918b3
("ipa: rkisp1: agc: Initialize enum controls with a list of values")
for the motivation. In summary, having a list of values is used as a sign
that the control is an enum in multiple places (e.g. `cam`, `camshark`).
