Create app_common and unify most displays.
This change moves all platform specific code from pw_display
into a new module: app_common. This new module is responsible
for initializig GPIO, SPI, creating the framebuffers and the
display. This allows for a second big change which is moving
pw_display from a facade to a concrete class. This is made
possible by the fact that it no longer need worry about the
display type or any platform details. These are all handled
by pw_display_driver and app_common respectively.
All configuration data (display size, pin assignments, etc.)
are now in the targets and app_common is resposible for
passing these down to the implementation for use.
