HACK: net: e1000: limit MRRS to 128

Memory read transactions (initiated from downstream devices) fail
with PCI controller in AM654 PG1.0 when MRRS is set to more than
128 Bytes. Force the MRRS to 128 Bytes for E1000 device here.

TODO:
This is marked as HACK because ideally this should be done
in AM65x specific way. But U-Boot lacks the infrastructure
to do that currently.
