misc: ele_api: Update ELE read common fuse API

Browse Source 
On iMX8ULP, the word index 1 is used to read OTP_UNIQ_ID with 4 words
data responsed. However this special index does not apply others.
So restrict the check to i.MX8ULP to avoid problem when reading from
fuse word 1 for others, such as i.MX93.

Also update header order
