s390/alternatives: Remove ALT_FACILITY_EARLY

Patch all alternatives which depend on facilities from the decompressor.
There is no technical reason which enforces to split patching of such
alternatives to the decompressor and the kernel.

This simplifies alternative handling a bit, since one alternative type is
removed.
