Page sizes are not interpreted correctly for E500/E500MC

http://cache.freescale.com/files/32bit/doc/ref_manual/E500CORERM.pdf - see 2.12.5.2 MAS Register 1 (MAS1), p. 2-41

According to these documents, variable page size for TLB1 is computed as 4K ** TSIZE.

However, QEMU always treats it as if it was 1K << TSIZE, even if options like "-cpu e500mc" are supplied to qemu.
