Thomas Huth 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.
