clk: msm: clock-osm: Fix check to write to the LLM OVERRIDE register 



On MSMCOBALT v2, the qcom,llm-sw-overr flag is no longer needed.
This causes an issue where the corresponding array in code is not
filled up but the check to make the writes to the llm register
still succeeds. This leads to us writing 0 to the register
erroneously multiple times. Fix this check.
