The MAX_TABLE_ENTRIES constant has a name that is too generic. As we
357786
want to declare a limit for boot menu entries, let's rename it to a more
357786
fitting MAX_BOOT_ENTRIES and set its value to 31 (30 boot entries and
357786
1 default entry). Also we move it from bootmap.h to s390-ccw.h to make
357786
it available for menu.c in a later patch.
