Haijun.Zhang a54d681132 esdhc: memset mmc struct before putting into use
struct mmc should be clear to all '0' after malloc to avoid
unexpect variable value.

Like mmc->has_init = xxx.
In this case mmcinfo will believe the card had been initialized before
and skip the initialization.

Test on P5040 and T4240,
