Merge tag 'omap-for-v4.1/fixes-0' into for-next

Fixes for omaps that were not considered urgent enough for the -rc cycle.

This is mostly to enable errata 798181 and thermal support for dra7,
configure ocp2scp for am437x, remove dead code for OMAP4_ERRATA_I688
and fix build warnings for omap1510 only config.
