[PATCH V2 1/9] clk: imx: clk-pll14xx: Switch to clk_hw based API

[Peng Fan <peng.fan@nxp.com>]

From: Peng Fan <peng.fan@nxp.com>

Switch the imx_clk_pll14xx function to clk_hw based API, rename
accordingly and add a macro for clk based legacy. This allows us to
move closer to a clear split between consumer and provider clk APIs.
