clk: Move the measure functionality from common clock framework 



Common Clock Framework(CCF) already has a clock ops hook `debug_init` which
could be used for the debugfs clock measure functionality. Remove the APIs
from the CCF and update the 'debug_init' clock ops to the clock types which
require the measure functionality.
