commit 8e9f25a290ae0016353c9ea13314c95fb3207812 upstream.
Each time SD/mmc phy is initialized, at times, in some of the attempts, phy fails to completes its initialization which results into timeout error. Per the HW spec, it is a pre-requisite to ensure a stable SD clock before a phy initialization is attempted.
