7618c0aefe s390-ccw: print carriage return with new lines
The sclp console in the s390 bios writes raw data,
leading console emulators (such as virsh console) to
treat a new line ('\n') as just a new line instead
of as a Unix line feed. Because of this, output
appears in a "stair case" pattern.

Let's print \r\n on every occurrence of a new line
in the string passed to write to amend this issue.

This is in sync with the guest Linux code in
drivers/s390/char/sclp_vt220.c which also does a line feed
conversion in the console part of the driver.

This fixes the s390-ccw and s390-netboot output like
$ virsh start test --console
Domain test started

Escape character is ^]
Network boot starting...

3639f93f91 pc-bios/s390-ccw: Add a write() function for stdio
The stdio functions from the SLOF libc need a write() function for
printing text to stdout/stderr. Let's implement this function by
refactoring the code from sclp_print().

af3bb73ab1 pc-bios/s390-ccw: Move ebc2asc to sclp.c
We will later need this array in a file that we will link to the
netboot code, too. Since there is some ebcdic conversion done
in sclp_get_loadparm_ascii(), the sclp.c file seems to be a good
candidate.

90806fec99 pc-bios/s390-ccw: Move libc functions to separate header
The upcoming netboot code will use the libc from SLOF. To be able
to still use s390-ccw.h there, the libc related functions in this
header have to be moved to a different location.
And while we're at it, remove the duplicate memcpy() function from
sclp.c.

Obtain the loadparm value stored in SCP Read Info by performing
a SCLP Read Info request.

Rename sclp-ascii.c to sclp.c to reflect the changed scope of
