ACPI: PAD: Rearrange notify handler installation and removal

Browse Source 
Use acpi_dev_install_notify_handler() and acpi_dev_remove_notify_handler()
for installing and removing the ACPI notify handler, respectively, which
allows acpi_pad_notify() and acpi_pad_remove() to be simplified quite a
bit.

No intentional functional impact.
