[PATCH] mmc: sdhci: replace mmc->parent with mmc_dev() for consistency

From: Jisheng Zhang
Date: Wed Mar 24 2021 - 03:51:13 EST

As pointed out by Ulf, "both "mmc->parent" and mmc_dev(mmc) are being
used in the entire c-file". Convert all the mmc->parent usage in all
sdhci host driver to mmc_dev() for consistency.
