nios2: dts: Fix tse_mac "max-frame-size" property

commit 85041e12418fd0c08ff972b7729f7971afb361f8 upstream.

The given value of 1518 seems to refer to the layer 2 ethernet frame
size without 802.1Q tag. Actual use of the "max-frame-size" including in
the consumer of the "altr,tse-1.0" compatible is the MTU.

Fixes: 95acd4c7b69c ("nios2: Device tree support")
Fixes: 61c610ec61bb ("nios2: Add Max10 device tree")
