target/ppc: Simplify checking for real mode in get_physical_address_wtlb()

Browse Source 
In get_physical_address_wtlb() the real_mode flag depends on either
the MSR[IR] or MSR[DR] bit depending on access_type. Extract just the
needed bit in a more straight forward way instead of doing unnecessary
computation.
