Bin Meng 298091f831 target/ppc: Add E500 L2CSR0 write helper 
Per EREF 2.0 [1] chapter 3.11.2:

The following bits in L2CSR0 (exists in the e500mc/e5500/e6500 core):

- L2FI  (L2 cache flash invalidate)
- L2FL  (L2 cache flush)
- L2LFC (L2 cache lock flash clear)

when set, a cache operation is initiated by hardware, and these bits
will be cleared when the operation is complete.

Since we don't model cache in QEMU, let's add a write helper to emulate
the cache operations completing instantly.
