net: phy: use c45 standard to detect link partner autoneg capability
Currently mii_lpa_mod_linkmode_lpa_t() checks bit LPA_LPACK to detect
whether link partner supports autoneg. This doesn't work correctly at
least on Aquantia AQCS109 when it negotiates 1000Base-T2 mode.
The "link partner is autoneg-capable" bit as defined by clause 45 is
set however. Better let's switch in general to use the clause 45
standard for link partner autoneg detection.
