Christophe Leroy 5aad0457ec target/ppc: 603: fix restore of GPRs 0-3 on rfi 
After a TLB miss exception, GPRs 0-3 must be restored on rfi.

This is managed by hreg_store_msr() which is called by do_rfi()

However, hreg_store_msr() does it if MSR[TGPR] is unset in the
passed MSR value.

The problem is that do_rfi() is given the content of SRR1 as
the value to be set in MSR, but TGPR bit is not part of SRR1
and that bit is used for something else and is sometimes set
to 1, leading to hreg_store_msr() not restoring GPRs.

So, do the same way as for POW bit, force clearing it.
