Probe the FMan MACs based on the device tree while retaining the legacy code/functionality. One notable change introduced here is that, for DM_ETH, the name of the interfaces is corrected to the fmX-macY format, that avoids the referral to the MAC block names which were incorrect for FMan v3 devices (i.e. DTSEC, TGEC) and had weird formatting (i.e. FM1@DTSEC6, FM1@TGEC1). The legacy code is left unchanged in this respect. Signed-off-by: Madalin Bucur <madalin.bucur@oss.nxp.com> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>
