Sansa AMS: Use small write delay for all non-HS cards including the internal SD to prevent data corruption.
Making this delay apply to all non-HS SD cards seems to fix some data corruption issues that came up with the switch to 4-bit widebus. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24019 a1c6a512-1295-4272-9138-f99709370657
