Subject: [PATCH] mfd: rk8xx-core: Check "system-power-controller" first

Commit 961748bb1555 ("dt-bindings: mfd: rk8xx: Deprecate rockchip,system-
power-controller") made the property "rockchip,system-power-controller"
deprecated in favor of the shorter, universal form "system-power-controller".
Following the updates to the board dts files, [1] make the favored property
name checked first, to save a few CPU cycles.
