Subject: ionic: remove support for mgmt device
Patch-mainline: v5.8-rc1
Git-commit: 77f972a7077d06d565243ecc192f45e1e5813cf1
References: bsc#1167773

We no longer support the mgmt device in the ionic driver,
so remove the device id and related code.

Fixes: b3f064e9746d ("ionic: add support for device id 0x1004")
