how to configure emmc devicetree on imx7d evm

[hyoungkikim]

hi experts 

I am trying to test by installing emmc on imx7d sabresd evm.
To enable emmc, I added usdhc3 status="okay" in the device tree and use pinctrl_usdhc3 as pinctrl setting

However, there is no pin description of MX7D_PAD_SD3_RESET_B_SD3_RESET
on schematics emmc reset ping is connected to GPIO_SD3_RESET_B. Do I need to set it in ushdc3 devcie tree using rst-gpios ?

thank you sincerely
