Since this patch may adversely affect a lot of users, I thought I'd post this
as an RFC first. I don't think the changes should affect any existing i8042
implementations, but can never be certain.

Limitations:

This patch does not overcome the problem of only being able to select
a single i8042 platform at compile-time. If compiling for a multiplatform
kernel, all platforms must use the DT version or only one platform
can have i8042 support.

The DT version assumes memory-mapped i8042 registers. It can not handle
IO-mapped modules (eg. x86)
