KVM: PPC: Make long relocations be ulong
On Book3S KVM we directly expose some asm pointers to C code as
variables. These need to be relocated and thus break on relocatable
kernels.
To make sure we can at least build, let's mark them as long instead
of u32 where 64bit relocations don't work.
This fixes the following build error:
WARNING: 2 bad relocations^M
> c000000000008590 R_PPC64_ADDR32 .text+0x4000000000008460^M
> c000000000008594 R_PPC64_ADDR32 .text+0x4000000000008598^M
Please keep in mind that actually using KVM on a relocated kernel
might still break. This only fixes the compile problem.
