This patch fixes a bug in the multiblock write tests where the written
data is read back for verifying one block at a time.  The tests in
mmc_test assumes that all cards are byte addressable.

This will cause the multi block write tests to fail, leading the user of
the mmc_test driver thinking there is something wrong with the sdhci
driver they are testing.

The start address for the block is calculated as: blocknum * 512. For
block addressable cards the blocknum alone should be used.

Due to a typo in the Basic Read test, it's currently identical to the
Basic Write test.  Fix this.

The mutex mmc_test_lock is initialized at every time mmc_test device
is probed. Probing another mmc_test device may break the mutex, if
the probe function is called while the mutex is locked.

This patch fixes it by statically initializing mmc_test_lock.

This reverts commit 48b5352e. Oversized
sg lists are not allowed anymore, and the core even checks for them in
debug mode, so this test is entirely incorrect.

Make it a bit more obvious that the card has been claimed by the
mmc_test driver so that people don't have to wonder why their block
device never shows up.

Add tests that make sure the driver properly checks the blocks and
blksz fields and doesn't assume the sg list has a size that perfectly
matches the current request.

Add a couple of tests to make sure the host driver handles highmem
memory pages properly. Unfortunately there is no way to guarantee an
allocation below 4 GB in i386, so it might give you addresses that
are out of reach for the hardware (OTOH, so will any other highmem
allocation in the kernel).

Clean up and reorganise the mmc_test driver so that it (hopefully)
is easier to extend with more complex tests.

We can only perform the tests on MMC and SD cards, so avoid binding
to any other type.

Add the ability to run just a single test case by writing the test
case number into the sysfs "test" file.
