s390: vmlinux.lds.S: Reorder sections

Browse Source 
[ Upstream commit 8d18ef04f9 ]

In the upcoming changes, the ELF_DETAILS macro will be extended with
the ".modinfo" section, which will cause an error:

>> s390x-linux-ld: .tmp_vmlinux1: warning: allocated section `.modinfo' not in segment
>> s390x-linux-ld: .tmp_vmlinux2: warning: allocated section `.modinfo' not in segment
>> s390x-linux-ld: vmlinux.unstripped: warning: allocated section `.modinfo' not in segment

This happens because the .vmlinux.info use :NONE to override the default
segment and tell the linker to not put the section in any segment at all.

To avoid this, we need to change the sections order that will be placed
in the default segment.
