emmc: Set a flag when all sampling points are valid [1/1]

Browse Source 
PD#SWPL-12209

Problem:
fixed SWPL-11917
When all the sample points are valid,
they fall into the changes of 111917

Solution:
flag is set when all sampling points are valid
so tuning does not enter the changes of 11197

Verify:
