QEMU doesn't model micro-architectural details which includes most chip errata. The ARM_ERRATA_798181 work around in the Linux kernel (see erratum_a15_798181_init) currently detects QEMU's cortex-a15 as broken and triggers additional expensive TLB flushes as a result. Change the MIDR to report what the latest silicon would (r4p0). We explicitly set the IMPDEF revidr bits to 0 because we don't need to set anything other than the silicon revision to indicate these flushes are not needed. This cuts about 5s from my Debian kernel boot with the latest 6.0rc1 kernel (29s->24s).
