ps2: disable keyboard during multiplexing probing

My machine does not have an AUX/Mouse port at all. As a result, the
commands all get sent to the keyboard, which confuses the keyboard and
it eventually resets. This is generally harmless, but it ends up
resetting the keyboard, which cancels the effect of the commands to set
the repeat rate and delay during boot.

By disabling the keyboard during this step, we can avoid interference
with it.

ps2: rename a constant also used in pads

ps2: added initial support for elantech pads.

* also added a license to ps2_alps.h
* added ps2_dev_sliced_command()
* moved some ps2 commands definitions to ps2_defs.h

* Implemented PS2_CMD_RESEND command handlig;

* Workaround for touchpad reset timeouts on some HP/Compaq KBCs. Looks like such
KBC marks the mouse reset request (xFF) as correctly sent (by xFA answer) but
does not wait enough time for the answer from touchpad. So complete answer
finally contains xFE xAA x00 bytes. The workaround detects this xFE xAA answer
and issues the RESEND (xFE) request to touchpad. This forces touchpad to resend
the last packet of data (xAA x00) that can be processed normally by the host;

* Fix for handling passthrough_command() call. The parent device was disabled at
start of processing command and was not re-enabled back in case any error return.
This fixes the touchpad "pass-through" feature handling on the same HP/Compaq HW.
This KBC has the "pass-through" capability marked ON but cannot handle it as
currently implemented - there is no answer from corresponding port. The parent
device stay in disabled state after this;

* Fix ps2_dev_publish() for handling passthrough devices (parent_dev != NULL)
This workaround postpone the publishing such device until the parent device
finishes it's opening and set the PS2_ENABLED_FALG. It prevent from mixing
the Synaptics multi-command sequences from synaptics_open() and ps2_dev_publish()
routines and failing both initializations;

Work in progress on a ALPS touchpad driver. The driver is roughly working but disabled at the moment. Its
more or less a copy of the synaptics driver. Next step is to refactor the movement generation and share the
code with the synaptics driver.

Patch by Clemens Zeilder:
* Implemented Synaptics touchpad support in the PS2 bus_manager by
refactoring/splitting the structure some and adding touchpad device
handling.
* Implemented Touchpad input_server device add-on
* Created Touchpad preflet for configuring advances Synaptics touchpad
options like scroll region (both horizontal and vertical) as well
as other neat stuff

Thanks a lot, Clemens!
