ps2_dev: shorter timeout for mouse reset

The keyboard is initialized after the mouse. When there is no mouse,
this timeout delays keyboard initialization noticeably (especially if
there is a mouse port multiplexer with several ports).

ps2: do not publish keyboard device until mouse probing is complete

For mouse probing to work reliably, it's important that we don't
simultaneously send commands to the keyboard as well. This normally
happens because we don't publish the keyboard device until the probing
is complete.

However, if the mouse probing results in the keyboard sending some
replies, this can be detected as a "hot plugin" and leads to publishing
the keyboard device a lot earlier.

To prevent this, disable the "hot plugin" feature until we are done
initializing. This way the keyboard device is published only after we
are done with the probing.

Fixes #17806

ps2: allow more selective tracing

In some cases, we don't need the full tracking of every byte received at
the PS2 level, but higher level traces from specific devices will be
enough.

ps2_dev encapsulate TRACING code

Avoid doing system_time() calls in a loop.
Is this even needed anymore?

Typo

Activate Elantech toucpad probe but fail.

Now we can see who has Elantech touchpad.
Driver is currently in very bad shape on my hw:
* mouse jumps
* mouse clicks maps to wrong button
* keyboard not working properly when enabled
* power button only works in force shutdown mode

PS/2 bus manager: style fixes only

ps2: disable elantech support until it's more functional

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

Ported ISA bus manager and PS/2 driver.

* 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;
