Remove pt_regs indirection and instead reference gp_regs directly, this
makes it portable across musl/glibc
Use PT_* constants defined in asm/ptrace.h
Move the file to ppc64 subdir and leave ppc empty
Fixes
../qemu-6.2.0/linux-user/host/ppc64/../ppc/host-signal.h:16:32: error: incomplete definition of type 'struct pt_regs'
return uc->uc_mcontext.regs->nip;
