Pin control fixes for the v3.17 series, only driver fixes:

Browse Source 
- SH-PFC (Renesas) r8a7791 CAN bus pin group problem
 - Rockchip (GPIO0 configuration)
 - Tegra-xusb (interrupt handling)
 - Exynos (GPIO interrupt locking)
 - Qualcomm (fix misleading example interrupts)
 - Minor non-critical fixes for abx500 and AT91 also sneaked in,
   because I initially intended this pull for post RC-1, hope it's
   still OK.
