Add necessary compatible flag for Cavium's DWC3 so
dwc3-of-simple will probe.

Instead of erroring out when we don't have clocks,
let's just avoid any calls to the clk API.

In dwc3_of_simple_remove() we are using clk_unprepare() before doing
any clk_disable(). If we enable Common CLK framework (CCF) and try to
unbind dwc3-of-simple driver, we see kernel WARN messages.
This patch fixes this kernel warning by using clk_disable_unprepare()
instead of clk_unprepare().

Rockchip platform merely enable usb3 clocks and
populate its children. So we can use this generic
glue layer to support Rockchip dwc3.

Add missing platform_set_drvdata() in dwc3_of_simple_probe(), otherwise
calling platform_get_drvdata() in remove returns NULL.
This is detected by Coccinelle semantic patch.

The check for < 0 is impossible now that
of_clk_get_parent_count() returns an unsigned int. Simplify the
code and update the types.

if we have a !PM kernel build, our runtime
suspend/resume callbacks will be left defined but
unused. Add a ifdef CONFIG_PM guard.

For simple platforms which merely enable some clocks
and populate its children, we can use this generic
glue layer to avoid boilerplate code duplication.
For now this supports Qcom and Xilinx, but if we
find a way to add generic handling of regulators and
optional PHYs, we can absorb exynos as well.
