Janosch Frank 4906a4e41c pc-bios: s390x: Fix bootmap.c zipl component entry data handling 
The two main types of zipl component entries are execute and
load/data. The last member of the component entry struct therefore
denotes either a PSW or an address. Let's make this a bit more clear
by introducing a union and cleaning up the code that uses that struct
member.

The execute type component entries written by zipl contain short PSWs,
not addresses. Let's mask them and only pass the address part to
jump_to_IPL_code(uint64_t address) because it expects an address as
visible by the name of the argument.
