mmc: core: Replace with already defined values for readability

BugLink: https://bugs.launchpad.net/bugs/1995637
[ Upstream commit e427266460826bea21b70f9b2bb29decfb2c2620 ]

SD_ROCR_S18A is already defined and is used to check the rocr value, so
let's replace with already defined values for readability.
