[PATCH 2/4] target/ppc: Fix XER access in gdbstub

[matheus . ferst]

From: Matheus Ferst <matheus.ferst@eldorado.org.br>

The value of XER is split in multiple fields of CPUPPCState, like
env->xer and env->so. To get/set the whole register from gdb, we should
use cpu_read_xer/cpu_write_xer.

Fixes: da91a00f191f ("target-ppc: Split out SO, OV, CA fields from XER")
