Merge tag 'omap-for-v4.4/dt-pt2' into for-next

Few more omap dts changes for v4.4 merge window, mostly to fix and clean
up some omap5 issues to allow adding other omap5 boards. Also some other
fixes and clean-up:

- Fix SDIO WLAN for omap5 that's been broken for a while. As further
  patches are still needed for wl18xx, no need for stable on this one.

- Move most of omap5 support into omap5-board-common.dtsi as most omap5
  boards seem to share the same basic set of devices.

- Add minimal IGEPv5 support using based on omap5-board-common.dtsi

- Remove now unneedes gpio hogging for dra72-evm

- Update Javier Martinez Canillas email address

- Change earlier IGEP boards to use IOPAD pinmux macros
