s390/setup: don't reserve memory that occupied decompressor's head

Browse source

There is no useful information within [STARTUP_NORMAL_OFFSET, HEAD_END] now.

But the memory region [0, STARTUP_NORMAL_OFFSET] is used by:
* lowcore
* kdump for swapping memory
* stand-alone zipl dumpers for code, data, stack and heap
