[U-Boot] [PATCH 1/2] drivers/ddr/fsl: Update clk_adjust of sdram_clk_cntl

[Shengzhou Liu]

The clk_adjust is of SDRAM_CLK_CNTL[5:8] 4-bits on MPC85xx and P-series,
but is of SDRAM_CLK_CNTL[5:9] 5-bits on T-series and LS-series SoCs.
We should update it to adapt the case that clk_adjust is odd data.
