This series adds a lux algorithm module to libipa and rkisp1. It is
modeled/copied from Raspberry Pi's, and estimates the lux level of the
image. This is used (so far only) by agc.

As there is no tuning support yet, this won't run (as in, you'll get
"missing tuning parameter" errors) and won't be merged until tuning
support is in so I'm just sending this in early for review.
