ARM: dts: rockchip: convert rk3188 to opp-v2

A patch from »ARM: dts: rockchip: Add BQ Edison2 QuadCore tablet« in state Maintainer-tree for linux-kernel

From: Heiko Stuebner <heiko.stuebner@...> Date: Wed, 10 Oct 2018 11:46:48 +0200

Commit-Message

The fact that OPPs specified only on cpu0 work is Linux specific and normally cpu frequencies should be specified for each cpu core. To facilitate this without needing to duplicate the frequency table each time, convert to opp-v2 before adding references to all cores. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
