of 400 khz Ident freq. Also misc formatting changes. Displaying the 400 khz ident frequency for the SD and uSD cards was not really useful information. This change displays the MCICLK frequency that we are running the cards at. The page now displays 0MHz until a card access and then will displays the set frequency and the actual frequency. The uSD display is now only displayed for those players with a uSD git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22684 a1c6a512-1295-4272-9138-f99709370657
