net: systemport: set dev->max_mtu to UMAC_MAX_MTU_SIZE

Browse source 
[ Upstream commit 54ddbdb024882e226055cc4c3c246592ddde2ee5 ]

The driver is already allocating receive buffers of 2KiB and the
Ethernet MAC is configured to accept frames up to UMAC_MAX_MTU_SIZE.

Fixes: bfcb813203e6 ("net: dsa: configure the MTU for switch ports")
