pinctrl: qcom: sc7280: Fix compile bug

Fix the compilation error, caused by updating constant variable.
Hence remove redundant constant variable, which is no more useful
as per new design.

The issue is due to some unstaged changes. Fix it up.

Fixes: 36fe26843d6d ("pinctrl: qcom: sc7280: Add clock optional check for ADSP bypass targets")
