sdk_dpaa: memac: fix AQR autoneg to lower than 10G partners

commit ac3c3de2ff287a31ea32e135ca889af339d3926d from
git://source.codeaurora.org/external/qoriq/qoriq-components/linux

Stop removing unsupported system side modes with AQR PHYs. Originally,
their removal didn't impact the modes advertised by the PHY. Since
auto-negotiation support was added to the aquantia driver, the
unsupported modes were no longer advertised. This prohibited the
PHY from negotiating with 1G link partners on LS1046ARDB.

Patch adapted from similar fix for the upstream DPAA1 Ethernet driver:
commit fddb5a50 ("dpaa_eth: support all modes with rate adapting PHYs")

Aquantia auto-negotiation:
commit 09c4c57f

 ("net: phy: aquantia: add support for auto-negotiation
configuration")
