net: dpaa: Fix <1G ethernet on LS1046ARDB 

As discussed in commit 73a21fa817 ("dpaa_eth: support all modes with
rate adapting PHYs"), we must add a workaround for Aquantia phys with
in-tree support in order to keep 1G support working. Update this
workaround for the AQR113C phy found on revision C LS1046ARDB boards.

Fixes: 12cf1b89a6 ("net: phy: Add support for AQR113C EPHY")
