Modified Files:
        src/sys/arch/aarch64/aarch64: vmt.c
        src/sys/dev/acpi: acpi_util.c acpi_util.h

Log Message:
PR/60655: vmt(4) probes the VMware backdoor unconditionally on aarch64

On ACPI systems only probe for vmt(4) when Hypervisor_Id in FADT reports
VMWare.

This helps avoid buggy hypervisors that don't implement a RAZ mdccsr_el0

Patch from Showta Ishizaki and slightly updated by me.
