I'm not sure about this. Perhaps it can use the implementation from  
imx8m/clock_imx8mm.c or there is a implementation needed explicit for
imx8qm? @Peng can you comment this? 

Until further notice I would just add these prototypes to fix the warnings:

+void init_clk_usdhc(u32 index);
+int fsl_esdhc_initialize(struct bd_info *bis, struct fsl_esdhc_cfg *cfg);

I will just add the prototype to fix it:

+void board_late_mmc_env_init(void);

thx for your review efforts.

Best regards,
