Merge tag 'omap-for-v4.9/fixes-for-rc-cycle' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
detection and gpadc patches are not strictly fixes, but I wanted to get
binding document typo fixed before it pops up on other boards. The
gpadc one liner was in the same series and I applied and pushed it out
already before noticing it could have waited. The list of changes is:

- Fix omap3 SoC features printed
- Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
- Add missing memory node for torpedo
- Initialize uart4_mask properly to avoid writing garbage to PRM registers
- Fix NULL pointer dereference for omap4 volt_data
- Add alias for omap5 gpadc needed by iio drivers
- Enable omap5 jack headset jack detection and fix it's binding typo
- Add missing memory node for logicpd-som-lv
- Fix wrong SMPS6 voltage for VDD-DDR3 for omap5
