This converts Berlin BG2 SoC dtsi to make use of the new DT clock
nodes for Berlin SoCs. While at it, also fix up twdclk which is
running at cpuclk/3 instead of sysclk.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@xxxxxxxxx>

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
