Sansa AMS: Run all SD cards within SD Specification frequencies.
Addition of a small write delay avoids data crc failures at lower MCICLK frequencies. Check the actual speed value from the card's CSD register to determine HS status. HS cards can run at twice the speed of standard speed SD cards. Internal cards & standard speed uSD now run at PCLK/4 = 15.5 MHz. HS uSD cards run at PCLK/2 = 31 MHz. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23901 a1c6a512-1295-4272-9138-f99709370657
