Revert "device: Add Kconfig options for D3COLD_SUPPORT and NO_S0IX_SUPPORT"

This reverts commit 655f7362e13ca49e3e13a822c916c7dc52573d74.

Reason for revert: Apparently, the change was not properly reviewed. It
not only contains conflicting name and description of the D3COLD
Kconfig, but also creates a conflict between existing devicetree and
Kconfig options for D3Cold/S3/S0ix.
