Subject: [PATCH 5.4 219/222] clk: imx7ulp: Correct DDR clock mux options

From: Anson Huang <Anson.Huang@....com>

commit 2e2b928a04bd74ea410da72bd60e1c5b06398276 upstream.

In the latest reference manual Rev.0,06/2019, the DDR clock mux
is extended to 2 bits, and the clock options are also changed,
correct them accordingly.

Fixes: b1260067ac3d ("clk: imx: add imx7ulp clk driver")
