The "highest" firmware the 5508 can go is 8.5.182.0. And this version can support the 3800.

As per https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html , use :
https://software.cisco.com/download/specialrelease/2702eede2b47a5c3bb40795bbe836af6
The use of the 8.5.182.0 , release is discouraged because of a few bugs
