ARM: dts: bcm283x: Fix critical trip point
During definition of the CPU thermal zone of BCM283x SoC family there
was a misunderstanding of the meaning "criticial trip point" and the
thermal throttling range of the VideoCore firmware. The latter one takes
effect when the core temperature is at least 85 degree celsius or higher
So the current critical trip point doesn't make sense, because the
thermal shutdown appears before the firmware has a chance to throttle
the ARM core(s).
Fix these unwanted shutdowns by increasing the critical trip point
to a value which shouldn't be reached with working thermal throttling.
