Kernel: Only do i8042 existence check via probing as a fallback

Browse source 
This caused an initialization failure of the i8042 when I tested on
bare metal. We cannot entirely get rid of this method as QEMU for
example doesn't indicate the existence of an i8042 via ACPI, but we can
get away with only doing the manual probing if ACPI is disabled or we
didn't get a 'yes' from it.
Increasing the number of maximum loops did eventually lead to a
successful return from the function, but would later fail the actual
self test.
