gpio: sysfs: move irq trigger flags to class-device data
Move irq trigger flags, which as sysfs-interface specific, to the class
device data.
This avoids accessing the gpio-descriptor flags field using non-atomic
operations without any locking, and allows for a more clear separation
of the sysfs interface from gpiolib core.
