Modify the testcase in 64-bit device & lower density field

1024x600 7" is the most popular panel solution in Tablet products.
According to the latest Android 5.1 CDD/CTS, this panel solution
with 64-bit devices becomes "Not applicable".
This new limitation has become the bottleneck of customer's
product planning.
