[RFC 5/9] clk: qcom: branch: Add macros to collapse definition

[Abel Vesa <abel.vesa@linaro.org>]

Add macros for a visually more compact branch clocks definition,
one for the common branch and one for branch_aon. They differ
from ops point of view, like their name suggest. There are also
three different macros to define the clk.hw.init depending on the
number and type of parent passed on as argument. Also, the macros
added here are only the ones used by gcc-sdm845 driver.
More will be added later on.
