s390/ipl: avoid usage of __section(.data)
bss section is cleared before ipl.c code is called or global variables are used nowadays. Remove stale comment and __section(.data) from few global variables. Also removes static/global variables initialization to 0. Signed-off-by: Vasily Gorbik <gor@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
