sandbox: clk: add clk enable/disable test code
Since we added clk enable_count and prograte clk child enabling
operation to clk parent, so add a new function sandbox_clk_enable_count
to get enable_count for test usage.
And add test code to get the enable_count after we enable/disable
the device clk.
