Catalin Marinas 2ac638fc57 arm64: kvm: mte: Hide the MTE CPUID information from the guests 
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.
