KVM does not support MTE in guests yet, so clear the corresponding field in the ID_AA64PFR1_EL1 register. In addition, inject an undefined exception in the guest if it accesses one of the GCR_EL1, RGSR_EL1, TFSR_EL1 or TFSRE0_EL1 registers. While the emulate_sys_reg() function already injects an undefined exception, this patch prevents the unnecessary printk.
