s390/Kconfig: make use of 'depends on cc-option'
Make use of 'depends on cc-option' to only display those Kconfig options for which compiler support is available. Add this for the MARCH and TUNE options which are the only options which may result in compile errors if the selected architecture is not supported by the compiler.
