net: ftmac100: set max_mtu to allow DSA overhead setting
In case ftmac100 is used with a DSA switch, Linux wants to set MTU
to 1504 to accommodate for DSA overhead. With the default max_mtu
it leads to the error message:
ftmac100 92000000.mac eth0: error -22 setting MTU to 1504 to include DSA overhead
ftmac100 supports packet length 1518 (MAX_PKT_SIZE constant), so it is
safe to report it in max_mtu.
