Currently the ITSS driver is built unconditionally. Add a Kconfig option to support enabling/disabling the inclusion of the ITSS driver depending on the platform.

I will have to squash this patch into the previous one, because the unconditional build causes issues for other x86 targets, see: https://dev.azure.com/bmeng/GitHub/_build/results?buildId=153&view=logs&...
Squashed in http://patchwork.ozlabs.org/patch/1232761/, and updated previous patch to conditionally built itss.o. see https://gitlab.denx.de/u-boot/custodians/u-boot-x86/commit/43709fa0888cc8064...
This way will keep bisectability.
applied to u-boot-x86, thanks!
