powerpc/irq: Rework helpers that manipulate MSR[EE/RI]
In preparation of porting PPC32 to C syscall entry/exit,
rewrite the following helpers as static inline functions and
add support for PPC32 in them:
__hard_irq_enable()
__hard_irq_disable()
__hard_EE_RI_disable()
__hard_RI_enable()
Then use them in PPC32 version of arch_local_irq_disable()
and arch_local_irq_enable() to avoid code duplication.
