[PATCH 1/2] pinctrl: intel: platform: Add INTC10B5 ACPI ID for Lunar Lake

Intel Lunar Lake platforms (Core Ultra 200V series) use INTC10B5 as
the ACPI hardware ID for the GPIO controller that manages power to
the integrated MIPI camera sensor.

Without this entry, the pinctrl-intel-platform driver does not bind
to the GPIO controller, causing int3472-discrete to report:

int3472-discrete INT3472:00: cannot find GPIO chip INTC10B5:00, deferring

This prevents the camera sensor from being powered on entirely.

Tested on: Dell Pro 14 Premium PA14250, Intel Core Ultra 7 266V
(Lunar Lake), Ubuntu 24.04, kernel 6.11.0-1016-oem
