Josef Söntgen c10ad4ff01 ps2_drv: back down after unsucessful AUX access
The driver might end up in an endless loop on systems that do not
contain an i8042 controller when probing the AUX interface. This
leads to busy looping and in the end to not annoucing the Input
service. Components that wait for the announcement of the service
will therefore hang as well.

Normally a service gets announced only if it is usable but in this
case this is inconvient because it renders all scenarios that use
the input_merger non working on x86 systems that only provide USB
input and do not have PS/2 at all.

Ideally, the PS/2 driver should only be started if the system needs it.
That is currently not feasible and for the time being we post-pone the
inevitable and back down after several unsucessful attempts to read
from the AUX interface while initializing the driver.

Fixes #1871.

README

This is the example operating system based on the Genode OS framework:

:_Init_: is the first real process in the system. The provided implementation
  uses a very simple XML parser to read its configuration files.

:_Drivers_: The example OS has basic drivers for frame buffer, mouse and
  keyboard input, the PCI bus, the real-time clock, and system-specific timers.

:_Server_: The only server in the example OS is Nitpicker, a
  minimal-complexity GUI server.

:_Test_: are also part of the example OS. You may have a look at the fork
  bomb as a simple system stress test.

:_Ldso_: is the dynamic linker used for loading executables that are linked
  against shared libraries.

:_Lib_: contains libraries used by the components of the OS repository,
  for example, the alarm framework.
