Subject: * dont compile audio codec drivers for bootloader, as we dont need
 them -> saves time * dont include uda1380 in bootloaders * fix to get rid of
 a nasty humming sound during is not uda1380 specific but iriver   specific
 and so put the fix into the bootloader. An other option was to   put
 audiohw_reset() into target tree... but i want to get rid of audiohw_reset
