SSD1306 needs VBAT when it is wired in charge pump configuration. This
patch adds support to the driver to enable VBAT regulator at init time.

It's rather confusing to have two patches with identical subjects and
descs (this and 4). And there's even an unrelated patch in between this
and the driver change...

Argh. I wonder how did this even happen. Something weird must have been
going on... there is only one such patch in branch I cherry-picked these
patches from. These last patches did not give me any errors and compiled
fine, so did not look too carefully at the results. Anyway, I'll squash
this into the earlier patch with the same subject in version 2 series.

Best regards,
Jyri
