PCI/pwrctrl: tc9563: Add GPIO auxiliary device support
The TC9563 embeds a GPIO controller used for per-port reset signals.
Create an auxiliary device for it so the gpio-tc9563 driver can register
the GPIO chip and enable DT-based GPIO lookups. Pass the tc9563 regmap to
the auxiliary device as its platform data.
The pwrctrl driver does not wait for the GPIO chip to be probed. The
per-port reset GPIO lookup, returning -EPROBE_DEFER until the chip is
registered, is added in the next patch.
