[SRU][Bionic][PATCH v3 6/6] ARM: dts: imx6: add thermal sensor and cooling cells

From: Lucas Stach <l.stach at pengutronix.de>

BugLink: https://bugs.launchpad.net/bugs/1840437

This allows a board to specify a custom thermal zone configuration
involving the SoC internal sensor, CPU and GPU nodes without having
to change those nodes.
