[PATCH v5 05/12] pc-bios: s390x: Remove unneeded dasd-ipl.c reset psw mask changes

[Janosch Frank]

jump_to_low_kernel() and the functions that it calls will already or
64 bit addressing into the reset psw mask when executing
jump_to_IPL_2() after the diag308 subcode 1.

The kernel proper is then branched to rather than doing a full PSW
change.
