ide-cd: remove struct atapi_capabilities_page (take 2)
* Remove struct atapi_capabilities_page. * Add ATAPI_CAPABILITIES_PAGE[_PAD]_SIZE define. v2: * The buf[] array access indexes were swapped between 'curspeed'/'maxspeed'. (Noticed by Borislav Petkov). Cc: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
