[U-Boot] [PATCH 4/8] net/fman: tune fman 10G driver to fit different SoC

[Shengzhou Liu]

- 10GEC1 uses mEMAC1 on T1024.
- 10GEC1/10GEC2 use mEMAC9/mEMAC10 on T2080/T4240.
- 10GEC3/10GEC4 use mEMAC1/mEMAC2 on T2080.
As there are anomalous naming for 10GEC on earlier SoCs(e.g. T2080/T4240),
now we introduce macro CONFIG_FSL_FM_TGEC_NORMAL_NAMING for those SoC
(e.g. T1024) with inerratic naming for 10GEC to fit different SoC.
