mmc: sdhci-xenon: fix PHY init clock stability
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.
