ACPI / utils: Rename acpi_dev_present()
acpi_dev_present() was originally named after pci_dev_present() to signify the similarity of the two functions. However Rafael J. Wysocki pointed out that the exported function acpi_dev_present() is easily confused with the non-exported acpi_device_is_present(). Additionally in ACPI parlance the term "present" usually refers to the "device is present" bit returned by the _STA control method, yet acpi_dev_present() merely checks presence in the namespace. It does not invoke _STA at all, let alone check the "device is present" bit. As suggested by Rafael, rename the function to acpi_dev_found() and adjust all existing call sites.
