s390 updates for 5.18-rc3

Browse source 
- Convert current_stack_pointer to a register alias like it is assumed if
   ARCH_HAS_CURRENT_STACK_POINTER is selected. The existing implementation
   as a function breaks CONFIG_HARDENED_USERCOPY sanity-checks.
 
 - Get rid of -Warray-bounds warning within kexec code.
 
 - Add minimal IBM z16 support by reporting a proper elf platform, and
   adding compile options.
 
 - Update defconfigs.
