[PATCH v2 kvmtool 02/30] hw/i8042: Compile only for x86

[Alexandru Elisei <alexandru.elisei@arm.com>]

The initialization function for the i8042 emulated device does exactly
nothing for all architectures, except for x86. As a result, the device
is usable only for x86, so let's make the file an architecture specific
object file.
