Actually both. execute_tuning should be run with actual I/O voltage in which
card is going to run. But here you are first running the execute_tuning()
may be at 3.3v/1.8v then changing the I/O voltage which I guess doesn't look
correct.
SD3.01 specification has specifically mentioned that first the I/O voltage
switch should happen and then only execute_tuning() should happen. So it's
better to check if the eMMC4.5 spec. also implies this restriction anywhere
or not.
