video: fbdev: remove unused auo_k190xfb drivers 

auo_k1900fb and auo_k1901fb drivers have been introduced six
years ago by following commits:

commit 2c8304d312 ("video: auo_k190x: add code shared by controller drivers")
commit 96b1d500e0 ("video: auo_k190x: add driver for AUO-K1900 variant")
commit 53027cdf2a ("video: auo_k190x: add driver for AUO-K1901 variant")

They never had any in-kernel user so just remove them (since
they are platform drivers they need corresponding platform
devices to be registered by kernel and it has never happened).

Provides support for epaper controllers from the K190X series

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.

serial updates, reducing the number of possible frames per second.
