[v4,07/33] target/ppc/mmu_common.c: Simplify checking for real mode

Message ID 27d34a0b33988d47aed3c45b1b8993b014a96e87.1715209155.git.balaton@eik.bme.hu (mailing list archive)

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.
