Subject: [PATCH v2 2/3] ARM: dts: rockchip: raise GPU trip point temperatures for veyron

The values match thorse used by the downstream Chrome OS 3.14
kernel, the 'official' kernel for veyron devices. Keep the critical
trip point for speedy at 90°C as in the downstream configuration.

Signed-off-by: Matthias Kaehlcke <mka@...omium.org>

Changes in v2:
- also raise temperature of critical trip point
- add entries at position in alphabetical order
- added entry to keep critical trip point for speedy at 90°C
