clk: introduce enable_count
As what Linux Kernel 5.3.0 provides when enable/disable clk, there is an enable_count in clk_core_disable/enable. Introduce enable_count to track the clk enable/disable count when clk_enable/disable for CCF. And Initialize enable_count to 0 when register the clk. And clk tree dump with enable_count will be supported, it will be easy for us to check the clk status with enable_count Signed-off-by: Peng Fan <peng.fan@nxp.com>
