pc-bios/s390-ccw: Fix indentation in start.S
start.S is currently indented with a mixture of spaces and tabs, which
is quite ugly. QEMU coding style says indentation should be 4 spaces,
and this is also what we are using in the assembler files in the
tests/tcg/s390x/ folder already, so let's adjust start.S accordingly.
