Octeontx2-af: Introduce mode group index
Kernel and firmware communicates via scratch register which is
64 bit in size.
[MODE_ID PORT AUTONEG DUPLEX SPEED CMD_ID OWNERSHIP ]
63-22 21-14 13 12 11-8 7-2 1-0
The existing MODE_ID bitmap can only support up to 42 modes.
To resolve the issue, the unused port field is modified as below
uint64_t reserved2:6;
uint64_t mode_group_idx:2;
'mode_group_idx' categorize the mode ID range to accommodate more modes.
To specify mode ID range of 0 - 41, this field will be 0.
To specify mode ID range of 42 - 83, this field will be 1.
mode ID will be still mentioned as 1 << (0 - 41). But the mode_group_idx
decides the actual mode range
