This reverts commit 1cfaf00.
We can actually run at any SPI speed - some cards run fine at 49 that wont run at 50. Our assumption about how the divisor worked was incorrect and we'd slow the SPI bus too much for no reason.
Removed the warning to the user too - a 25MHz SPI is plenty fast here. Need to still update the troubleshooting docs to take the info in the Slow SPI article into account.
