target/arm: Use acpi_ghes_present() to see if we report ACPI memory errors
The virt_is_acpi_enabled() function is specific to the virt board, as is the check for its 'ras' property. Use the new acpi_ghes_present() function to check whether we should report memory errors via acpi_ghes_record_errors(). This avoids a link error if QEMU was built without support for the virt board, and provides a mechanism that can be used by any future board models that want to add ACPI memory error reporting support (they only need to call acpi_ghes_add_fw_cfg()).
