Subject: [PATCH 0621/2940] net: phy: Also request modules for C45 IDs
Logic of phy_device_create() requests PHY modules according to PHY ID
but for C45 PHYs we use different field for the IDs.
Let's also request the modules for these IDs.
Changes from v1:
- Only request C22 modules if C45 are not present (Andrew)
