Subject: [PATCH v2 1/5] arm64: dts: qcom: msm8916: Add the clocks for the APCS mux/divider

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@...aro.org>

Specify the clocks that feed the APCS mux/divider instead of using
default hardcoded values in the source code.

The driver still supports the previous bindings; however with this
update it we allow the msm8916 to access the parent clock names
required by the driver operation using the device tree node.

Changes since v1:
-Swapped order of "pll" and "aux" clocks, in order to not break DT
backwards compatibility. (In case no clock-names are given, "pll" still
has to be the first clock).
