[PATCH 1/3] PCI/pwrctrl: Bind a pwrctrl device if clocks are present

[Sean Anderson <sean.anderson@linux.dev>]

Since commit 66db1d3cbdb0 ("PCI/pwrctrl: Add optional slot clock for PCI
slots"), power supplies are not the only resource PCI slots may create.
Also create a pwrctrl device if there are any clocks.
