net: dsa: microchip: add support for credit based shaper

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.
