====================
Fix QCA808X WoL Issue

Restore WoL (Wake-on-LAN) enablement via MMD3 register 0x8012 BIT5 for
the QCA808X PHY. This change resolves the issue where WoL functionality
was not working due to its unintended removal in a previous commit.

Refactor at8031_set_wol() into a shared library to enable reuse of the
Wake-on-LAN (WoL) functionality by the AT8031, QCA807X and QCA808X PHY
drivers.
