LAN937x switch family, KSZ9477, KSZ9567, KSZ9563 and KSZ8563 supports
the credit based shaper. But there were few difference between LAN937x and KSZ
switch like
- number of queues for LAN937x is 8 and for others it is 4.
- size of credit increment register for LAN937x is 24 and for other is 16-bit.
This patch series add the credit based shaper with common implementation for
LAN937x and KSZ swithes.

v1 -> v2
- Added the check for divide by zero in cinc_cal()
- Port queue is splitted based on dev->info->tc_num_queues

RFC -> Patch v1
- Rebased to latest net-next
