Christian Marangi c5b12fc02a airoha: Introduce support for Airoha AN7583 SoC
Introduce initial support for Airoha AN7583 SoC and add all the required
patch for basic functionality of the SoC.

Airoha AN7583 is based on Airoha EN7581 SoC with some major changes on
the PHY handling and Serdes. It can be see as a lower spec of EN7581
with modern and simplified implementations.

All the patch are sent upstream and are pending revision. Support for
PCIe and USB will come later as soon as DT structure is accepted
upstream.

Subject: [PATCH 2/3] net: dsa: mt7530: Add AN7583 support
Add Airoha AN7583 Switch support. This is based on Airoha EN7581 that is
based on Mediatek MT7988 Switch.
Airoha AN7583 require additional tweak to the GEPHY_CONN_CFG register to
make the internal PHY work.
