[net-next v3] net: ftgmac100: refactor getting phy device handle
From: Jacky Chou
Date: Tue Oct 22 2024 - 04:43:06 EST
Consolidate the handling of dedicated PHY and fixed-link phy by taking
advantage of logic in of_phy_get_and_connect() which handles both of
these cases, rather than open coding the same logic in ftgmac100_probe().

v2:
- enable mac asym pause support for fixed-link PHY
- remove fixes information
v3:
- Adjust the commit message
