acpi_device_is_present() checks the present or functional bits
from the cached copy of _STA.

A few places open-code this check. Use the helper instead to
improve readability.

Jonathan Cameron suggests "Pull this one out and send it upstream in
advance of the rest" so let's do that. See
https://lore.kernel.org/r/20230914130455.00004434@Huawei.com/

So, let's get this upstream to reduce the number of outstanding patches
for aarch64 vcpu hotplug.
