Raju Rangoju 9439a661c2 amd-xgbe: fix MAC_TCR_SS register width for 2.5G and 10M speeds 
Extend the MAC_TCR_SS (Speed Select) register field width from 2 bits
to 3 bits to properly support all speed settings.

The MAC_TCR register's SS field encoding requires 3 bits to represent
all supported speeds:
  - 0x00: 10Gbps (XGMII)
  - 0x02: 2.5Gbps (GMII) / 100Mbps
  - 0x03: 1Gbps / 10Mbps
  - 0x06: 2.5Gbps (XGMII) - P100a only

With only 2 bits, values 0x04-0x07 cannot be represented, which breaks
2.5G XGMII mode on newer platforms and causes incorrect speed select
values to be programmed.

Fixes: 07445f3c7c ("amd-xgbe: Add support for 10 Mbps speed")
