pc-bios/s390-ccw: fix loadparm initialization and int conversion
Rename the loadparm char array in main.c to loadparm_str and
increased the size by one byte to account for a null termination
when converting the loadparm string to an int via atoui. We
also allow the boot menu to be enabled when loadparm is set to
an empty string or a series of spaces.
