[Qemu-devel] [PATCH v3 09/38] target-microblaze: Conditionalize setting of PVR11_USE_MMU

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

Conditionalize setting of PVR11_USE_MMU on the use_mmu
CPU property, otherwise we may incorrectly advertise an
MMU via PVR when the core in fact has none.
