net: mdio: fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
| drivers/net/mdio/mdio-xgene.c:338:13: warning: cast to smaller integer
| type 'enum xgene_mdio_id' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 338 | mdio_id = (enum xgene_mdio_id)of_id->data;
This is due to the fact that `of_id->data` is a void* while `enum
xgene_mdio_id` has the size of an int. This leads to truncation and
possible data loss.
