Subject: [PATCH v2 08/10] ARM: dts: berlin: convert BG2CD to DT clock nodes
This converts Berlin BG2CD SoC dtsi to make use of the new DT clock
nodes for Berlin SoCs. Also add a binding include to ease core clock
references.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@...il.com>

Changelog:
v1->v2:
- dropped of_clk_create_name() usage required unique node names for
clocks and plls
- added clock-output-names to allow fixed-factor-clock to find its
parent name
