gpiolib: acpi: Change type of dflags

Most of the code inside GPIO library is using enum gpiod_flags.
Some of the function still operate with unsigned int.

In order to be more consistent and better type checking, convert
acpi_gpiochip_parse_own_gpio() to use enum gpiod_flags instead of
unsigned int.
