* 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
