Nicholas Piggin 54071e4176 powerpc/64s: micro-optimise __hard_irq_enable() for mtmsrd L=1 support 
Book3S minimum supported ISA version now requires mtmsrd L=1. This
instruction does not require bits other than RI and EE to be supplied,
so __hard_irq_enable() and __hard_irq_disable() does not have to read
the kernel_msr from paca.

Interrupt entry code already relies on L=1 support.
