PPC: Suppress gcc warnings with -Wtype-limits
The hack added by c5b76b381081680633e2e0a91216507430409fb2 was notenough to avoid warnings with gcc flag -Wtype-limits. Add a new macroto fix both problems.

target-ppc: fix RFI by clearing some bits of MSR
Since commit 2ada0ed, "Return From Interrupt" is broken for PPC processorsbecause some interrupt specifics bits of SRR1 are copied to MSR.
SRR1 is a save of MSR during interrupt.During RFI, MSR must be restored from SRR1....
target-ppc: change DCR helpers to target_long arguments
The recent transition to always have the DCR helper functions take 32 bitvalues broke the PPC64 target, as target_long became 64 bits there.

PPC: Make DCR uint32_t
For what I know DCR is always 32 bits wide, so we should also use uint32_t topass it along the stacks.

Fix the alternate time base the same way as the default timebase. SPR_ATBLshould return a 64-bit value on 64 bit implementations.
PPC64: Fix timebase
On PPC we have a 64-bit time base. Usually (PPC32) this is accessed usingtwo separate 32 bit SPR accesses to SPR_TBU and SPR_TBL.
On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full64 bits as return value. If we only take the lower ones, fine. But Linux...
