mmc_test: add performance tests
mmc_test provides tests aimed at testing SD/MMC hosts. This patch adds
performance tests.
It is advantageous to have performance tests in a kernel
module like mmc_test for the following reasons:
- transfer times can be measured very accurately
- arbitrarily large transfers are possible
- the effect of contiguous vs scattered pages
can be determined
The new tests are:
23. Best-case read performance
24. Best-case write performance
25. Best-case read performance into scattered pages
26. Best-case write performance from scattered pages
27. Single read performance by transfer size
28. Single write performance by transfer size
29. Single trim performance by transfer size
30. Consecutive read performance by transfer size
31. Consecutive write performance by transfer size
32. Consecutive trim performance by transfer size
