[PATCH v2 2/4] clk: Use 'parent' to shorten lines in __clk_core_init()

[Stephen Boyd <sboyd@kernel.org>]

Some lines are getting long in this function. Let's move 'parent' up to
the top of the function and use it in many places whenever there is a
parent for a clk. This shortens some lines by avoiding core->parent->
indirections.
