pc-bios/s390-ccw: Clarify alignment is in bytes

Browse Source 
The assembler directive .align [1] has architecture-dependent behavior,
which may be ambiguous for the reader. Some architectures perform the
alignment in bytes, others in power of two. s390 does in bytes.

Use the directive .balign [2] instead, to clarify that the alignment
request is in bytes. No functional change.
