[PATCH 4/8] platform/x86: x86-android-tablets: Remove invalid_aei_gpiochip support

[Hans de Goede <hdegoede@redhat.com>]

x86_dev_info.invalid_aei_gpiochip is no longer used by any boards
and the x86-android-tablets code should not use the gpiolib private
acpi_gpiochip_free_interrupts() function.

Closes: https://lore.kernel.org/platform-driver-x86/20230905185309.131295-12-brgl@bgdev.pl/
