mmc: sdhci-esdhc-imx: name esdhc specific definitions with ESDHC_ prefix
Rename esdhc local definitions with ESDHC_ rather than SDHCI_ prefix, so that we can distinguish them from SDHCI core definitions from name. A couple of bit fields are also changed use shift for consistency and better readability.
