mmc_test: block addressed cards
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.
