[#3682] Fix bug when fail to detect MMC on BF537
SPI_MMC use SPI_MMC_INIT_SPEED to detect MMC card. Actually,
before SVN commit 3801, the SPI framework uses the default
max_speed_hz from board file to detect MMC card. And it works.
In SVN commit 3801, it modified the SPI framework Blackfin driver
to setup SPI baud rate according to every spi_transfer.speed_hz.
Then it fail to detect MMC.
So as a result, use lower SPI_MMC_INIT_SPEED to detect MMC card
will always fail. Use default SPI_MMC_MAX_SPEED to fix this bug.
