Andy Shevchenko 130067ed15 mmc_test: move files from sysfs to debugfs
As proposed by Greg K-H it is more logical to keep files for the mmc_test
driver under debugfs.

Additionally this patch brings seq_file API for show() method.  It allows
to write unlimited data to the file.

Example of usage:
  # mount -t debugfs none /sys/kernel/debug
  # modprobe mmc_test
    [  581.395843] mmc_test mmc0:0001: Card claimed for testing.
  # echo 25 > /sys/kernel/debug/mmc0/mmc0\:0001/test
    [  604.568542] mmc0: Starting tests of card mmc0:0001...
    [  604.582733] mmc0: Test case 25. Best-case read performance into scattered pages...
    [  604.923553] mmc0: Transfer of 8192 sectors (4096 KiB) took 0.124664314 seconds (33644 kB/s, 32856 KiB/s)
    [  604.933227] mmc0: Result: OK
    [  604.936248] mmc0: Tests completed.
  # cat /sys/kernel/debug/mmc0/mmc0\:0001/test
    Test 25: 0
