x86: i8042: Correctly initialize the controller
The existing i8042 keyboard controller driver has some issues.
First of all, it does not issue a self-test command (0xaa) to the
controller at the very beginning. Without this, the controller
does not respond to any command at all. Secondly, it initializes
the configuration byte register to turn on the keyboard's interrupt,
as U-Boot does not normally allow interrupts to be processed.
Finally, at the end of the initialization routine, it wrongly
sets the controller to disable all interfaces including both
keyboard and mouse.

input: simplify key_matrix_decode_fdt()
We know the exact property names that the code wants to process. Look
these up directly with fdt_get_property(), rather than iterating over
all properties within the node, and checking each property's name, in
a convoluted fashion, against the expected name.
