[PATCH v2 02/10] gpiolib: define GPIOD_FLAG_SHARED

From: Bartosz Golaszewski <bartosz.golaszewski at linaro.org>
Define a new GPIO descriptor flag for marking pins that are shared by
multiple consumer. This flag will be used in several places so we need
to do it in advance and separately from other changes.
