gpiolib: acpi: Program debounce when finding GPIO

Browse source

When soc-button-array looks up the GPIO to use it calls acpi_find_gpio()
which will parse _CRS.

acpi_find_gpio.cold (drivers/gpio/gpiolib-acpi-core.c:953)
gpiod_find_and_request (drivers/gpio/gpiolib.c:4598 drivers/gpio/gpiolib.c:4625)
gpiod_get_index (drivers/gpio/gpiolib.c:4877)

The GPIO is setup basically, but the debounce information is discarded.
The platform will assert what debounce should be in _CRS, so program it
at the time it's available.
