[PATCH 2/2] arm64: dts: sprd: sc9860: Simplify clock nodes

["Rob Herring (Arm)" <robh@kernel.org>]

The various "syscon" nodes in SC9860 are only referenced by clock
provider nodes in a 1:1 relationship, and nothing else references the
"syscon" nodes. There's no apparent reason for this split. The 2 nodes
can simply be merged into 1 node. The clock driver has supported using
either "reg" or "sprd,syscon" to access registers from the start, so
there shouldn't be any compatibility issues.

With this, DT schema warnings for missing a specific compatible with
"syscon" and non-MMIO devices on "simple-bus" are fixed.
