Pin control fixes for the v4.2 series:

- Some dead defines dropped from the Samsung driver, was
   targeted for -rc2 but got delayed
 - Drop the strict mode from abx500, this was too strict
 - Fix the R-Car sparse IRQs code to work as intended
 - Fix the IRQ code for the pinctrl-single GPIO backend to not
   enforce threaded IRQs
 - Clear the latched events/IRQs for the Broadcom BCM2835
   driver
 - Fix up debugfs for the Freescale imx1 driver
 - Fix a typo bug in the Schmitt Trigger setup in the LPC18xx
   driver

Pull pin control fixes from Linus Walleij:
 "Here are some overly ripe pin control fixes for the v4.2 series.

  They got delayed because of various crap commits and having to clean
  and rinse the patch stack a few times.  Now they are however looking
  good.

   - some dead defines dropped from the Samsung driver, was targeted for
     -rc2 but got delayed
   - drop the strict mode from abx500, this was too strict
   - fix the R-Car sparse IRQs code to work as intended
   - fix the IRQ code for the pinctrl-single GPIO backend to not enforce
     threaded IRQs
   - clear the latched events/IRQs for the Broadcom BCM2835 driver
   - fix up debugfs for the Freescale imx1 driver
   - fix a typo bug in the Schmitt Trigger setup in the LPC18xx driver"
