kernel: 5.10: backport at803x QCA83xx phy support improvements

Browse Source 
This commit add accepted upstream patches that improve & tidy qca83xx support.
1 - Split qca8327 to A & B variants, identifiable by phy_id
2 - Add suspend/resume support to qca8xx phys
3 - Tidy spacing and phy naming.

Subject: net: phy: at803x: add support for qca 8327 A variant internal phy
For qca8327 internal phy there are 2 different switch variant with 2
different phy id. Add this missing variant so the internal phy can be
correctly identified and fixed.

Subject: net: phy: at803x: add resume/suspend function to qca83xx phy
Add resume/suspend function to qca83xx internal phy.
We can't use the at803x generic function as the documentation lacks of
any support for WoL regs.
