net: phy: nxp-c45-tja11xx: fix the PHY ID mismatch issue when using C45
TJA1103/04/20/21 support both C22 and C45 accessing methods.
The TJA11xx driver has implemented the match_phy_device() API.
However, it does not handle the C45 ID. If C45 was used to access
TJA11xx, match_phy_device() would always return false due to
phydev->phy_id only used by C22 being empty, resulting in the
generic phy driver being used for TJA11xx PHYs.
Therefore, check phydev->c45_ids.device_ids[MDIO_MMD_PMAPMD] when
using C45.
