As noted in the comment, the PRIbits field in ICV_CTLR_EL1 is supposed to match the ICH_VTR_EL2 PRIbits setting; that is, it is the virtual priority bit setting, not the physical priority bit setting. (For QEMU currently we always implement 8 bits of physical priority, so the PRIbits field was previously 7, since it is defined to be "priority bits - 1".)
