Summary

According to the HW FPGA spec, add mdio config on RTM_L and RTM_R.
These MDIO controllers start and end address is illustrated in the following chart.

BUS	address
1	0x200
2	0x220
3	0x240
4	0x260
5	0x280
6	0x2a0
7	0x2c0
8	0x2e0
9	0x300
10	0x320
11	0x340
12	0x360
13	0x380
14	0x3a0
15	0x3c0
16	0x3e0

@chee-zhang - can you share the phyId (and phy core id) to MDIO controller id mapping. I want to explore how we can keep this information in platform_manager.
