  pc-bios/s390-ccw: store proper subsystem information word

POP chapter 17 requires to store a subsystem information word at 184
during IPL. Furthermore bytes 188-191 should be zero. The bootmap might
contain data blocks that are written to the first page. We have to
write these values after we processed the bootmap and before the final
IPL.

  s390x/css: reflect cpa in scsw

We neglected to update the the channel-program-address field of the scsw
after completion of the start or the halt function: Fortunately, Linux
didn't miss it so far. Let's update it for the cases where the cpa is
expected to be valid; in some cases, the cpa is 'unpredictable', so we
leave it untouched.
