Add #ifdef HAVE_MULTIDRIVE to HS timings switch for uSD cards.
Internal cards are v1 sd cards so no need to include this code for the clip. Move transition from STBY -> TRAN-> STBY states inside the if(sd_v2) conditional check for HS switch as it's not needed for non HS cards. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23331 a1c6a512-1295-4272-9138-f99709370657
