Hi Wolfgang,

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&...
