net: aquantia: Fix actual speed capabilities reporting

Browse Source 
[ Upstream commit e4d02ca04c6d48ab2226342a1c4ed54f1dbb72bd ]

Different hardware device Ids correspond to different maximum speed
available. Extra checks were added for devices D108 and D109 to
remove unsupported speeds from these device capabilities list.
