msm: camera: icp: Return CAM_MAX_VOTE if matching index not found 



If no matching index found in the clk info clk rate table
for the input base_clk rate, i.e if base_clk rate value
is greater than the max value in the clk info table,
return CAM_MAX_VOTE so that caller knows the passed base clk
value is higher than max value in the clk table. This helps
in determining whether the clk is overclocked and thus
reducing as required.
