Add support for the new AE controls in the rkisp1 pipeline handler, and
in the IPA.

No change in v2

Initial version:
It seems that the rkisp1 pipeline handler doesn't properly expose its
control capabilities? And even though it exposed AeEnable with both true
and false it didn't expose or handle AnalogueGain nor ExposureTime
either? So I just simply replaced AeEnable with ExposureTimeMode for
