Add four tests for read and write performance per different transfer size, 4k to 4M. * Read using blocking mmc request * Read using non-blocking mmc request * Write using blocking mmc request * Write using non-blocking mmc request
The host dirver must support pre_req() and post_req() in order to run the non-blocking test cases.

Remove this error check. It is fine to run this test without these hooks, but there will be no performance gain compared to blocking request.

I got this comment from Linus W. Use TEST_AREA_MAX_SIZE instead of hard coded 128*1024*1024. update all relevant functions.
