Currently on a FSP based P9 system load_capp_code() expects CAPP ucode lid header to have eye-catcher magic of 'CAPPPSLL'. However skiboot currently supports CAPP ucode only lids that have a eye-catcher magic of 'CAPPLIDH'. This prevents skiboot from loading the ucode with this error message: CAPP: ucode header invalid We fix this issue by updating load_capp_ucode() to use the eye-catcher value of 'CAPPLIDH' instead of 'CAPPPSLL'.
