ARM: dts: add pinmux and tuning settings for HS200/SDR104
The pinmux and tuning settings are from
https://source.codeaurora.org/external/imx/linux-imx/tree/arch/
arm/boot/dts/imx7s.dtsi?h=imx_4.9.11_1.0.0_ga
https://source.codeaurora.org/external/imx/linux-imx/tree/arch/
arm/boot/dts/imx7d-sdb.dts?h=imx_4.9.11_1.0.0_ga
To support HS200 and SDR104, we need change pinmux settings dynamically.
And configure tuning step and start tuning tap, otherwise you may
see tuning failure.
