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.

Make reset gpio devicetree property optional. Depending on the board
designing there may not be a dedicated gpio for resetting the
display. Without a proper reset there may be some junk in the display
memory at probe time, so in such a case the display memory is cleared
before turning it on. The devicetree binding document is also updated.

Remove reset-active-low from the devicetree binding document. The actual
implementation has never been there in the driver code and there is no
reason to add it because the gpiod API supports gpio flags, including
GPIO_ACTIVE_LOW, directly trough its own devicetree binding.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
