platform: remove unnecessary Kconfig defaults

Remove unnecessary 'n' defaults in sof/src/plaform Kconfig. This doesn't
affect any current build as 'n' is the default if not set otherwise.

By removing the unconditional defaults, it becomes possible to set
defaults later in board/family specific Kconfig.defconfig files.
