Some boards have an i8042 device. Enable the driver for all x86 boards, and
add a device tree node for those which may have this keyboard.

Also adjust the configuration so that i8042 is always separate from the VGA,
and rename the stdin driver accordingly. With this commit the keyboard will
not work, but it is fixed in the next commit.

At present the i8042 driver has its own logic and keymaps. In an effort to
unify the code, move it over to use the input library. This changes most of
the keycode-processing logic since it is now in that library. The main
responsibilities of the driver are now to handle the LEDs, deal with the
PS/2 extended keycodes and initialise the the keyboard.

Generally the input library handles processing of a list of scanned keys.
Repeated keys need to be generated based on a timer in this case, since all
that is provided is a list of keys current depressed.

Keyboards which do their own scanning will resend codes when they want to
inject a repeating key. Provide a function which tells the input library to
accept repeating keys and not to try to second-guess the caller.

Most keyboards can be scanned to produce a list of the keycodes which are
depressed. With the i8042 keyboard this scanning is done internally and
only the processed results are returned.

In this case, when a key is pressed, a 'make' code is sent. When the key
is released a 'break' code is sent. This means that the driver needs to
keep track of which keys are pressed. It also means that any protocol error
can lead to stuck keys.

In order to support this type of keyboard, add a function when can be used
to provide a single keycode and either add it to the list of what is pressed
or remove it from the list. Then the normal input_send_keycodes() function
can be used to actually do the decoding work.

Add debugging to display the ASCII characters written to the input queue
also.

CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and
CONFIG_CONSOLE_TIME are not used by any board. The implementation is not
great and stands in the way of a refactor of i8042. Drop these for now.
They can be re-introduced quite easily later, perhaps with driver-model
real-time-clock (RTC) support.

When reintroducing, it might be useful to make a few changes:
- Blink time would be more useful than blink count
- The confusing #ifdefs should be avoided
- The time functions should support driver model
- It would be best keyed off console_tstc() or some similar idle loop
    rather than a particular input driver (i8042 in this case)
