video: auo_k190x: add code shared by controller drivers

Browse Source 
The AUO-K190X controllers share a very similar set of commands and
can therefore also share most of the driver code.

Provides support for epaper controllers from the K190X series
of AUO. These controllers can be used to drive epaper displays
from Sipix.
This option enables the common support, shared by the individual
controller drivers. You will also have to enable the driver
for the controller type used in your device.
