[PATCH 3/3] firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails

[Sarangdhar Joshi]

When devm_clk_get fails for core clock, the failure was ignored
and the core_clk was explicitly set to NULL so that other
remaining clocks can be queried. However, now that we have a
clean way of expressing the clock dependency, return failure when
devm_clk_get fails for core clock.
