[PATCH 5/9] target/ppc: Use ppc_interrupts_little_endian in powerpc_excp

[Fabiano Rosas]

The ppc_interrupts_little_endian function is suitable for determining
the endianness of interrupts for all Book3S CPUs.

(I'm keeping the MSR check for the rest of the CPUs, but it will go
away in the next patch.)
