Merge tag 'bcm2835-dt-64-next-2017-06-08' into devicetree-arm64/next

This pull request brings in the switch to sdhost for MMC on RPi3
(improving storage performance and leaving sdhci for wireless), and
the correct CPU thermal coefficients.

The thermal changes required a merge from bcm2835-dt-next, where the
nodes were added.
