Subject: [PATCH v2 13/18] serial: intel: Replace clk_enable/clk_disable with clk generic API

The clk driver has introduced new clock APIs that replace
the existing clk_enable and clk_disable.
 -clk_enable() APIs is replaced with clk_prepare_enable().
 -clk_disable() API is replaced with clk_disable_unprepare().
