s390/boot: disable address-of-packed-member warning
Get rid of gcc9 warnings like this:
arch/s390/boot/ipl_report.c: In function 'find_bootdata_space':
arch/s390/boot/ipl_report.c:42:26: warning: taking address of packed member of 'struct ipl_rb_components' may result in an unaligned pointer value [-Waddress-of-packed-member]
42 | for_each_rb_entry(comp, comps)
| ^~~~~
This is effectively the s390 variant of commit 20c6c1890455
("x86/boot: Disable the address-of-packed-member compiler warning").
