[PATCH V2 1/4] clk: imx: pll14xx: use writel_relaxed

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

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

writel has a barrier, however that barrier is not needed,
because device memory mapping is nGnRE mapping and access is
in order and clk driver has spin lock or other lock to make
sure write finished.
