FROMLIST: ufs: change the way to complete fDeviceInit

Currently, UFS driver checks if fDeviceInit
is cleared at several times, not period. This patch
is to wait its completion with the period, not retrying.
Many device vendors usually provides the specification on
it with just period, not a combination of a number of retrying
and period. So it could be proper to regard to the information
coming from device vendors.
