clk: Add separate function to print clocks enabled during suspend 



When debug_suspend is set to true and the low power code invokes the
function to print the enabled clocks during suspend the function fails to
execute the do while loop in clock_debug_print_enabled_clocks, so separate
out the function to handle the same.
