test/qtest/aspeed_smc-test: Support to test all CE pins 

Currently, these test cases only support to test CE0. To test all CE pins,
introduces new ce and node members in TestData structure. The ce member is used
for saving the ce index and node member is used for saving the node path,
respectively.
