[PATCH v1 1/2] clk: qcom: rpmh: skip undefined clocks when registering

[Taniya Das <tdas@codeaurora.org>]

When iterating over a platform's available clocks in clk_rpmh_probe(),
check for undefined (null) entries in the clocks array.  Not all
clock indexes necessarily have clocks defined. Also remove referencing
the clock name before valid hardware.
