At the very early stage when PHY ID is being auto-detected, the
PHY device is not yet instantiated and rswitch_etha .phydev is
still NULL. Add missing check for this condition and perform C22
fallback access in this PHY ID auto-detection case.

Set RMII reference clock output to enabled (1) by default for VSC8541
PHY in RMII mode. The RMII specification requires a 50MHz reference
clock, and many board designs expect the PHY to provide this clock to
the MAC controller.

Previously, the driver defaulted rmii_clk_out to 0 (disabled) for all
interface modes, which caused the PHY to not output the required 50MHz
clock. This resulted in MAC-PHY communication failures and prevented
network operations like DHCP from working on RMII-configured boards.

This change alligns with the hardware power-up default behavior and
aligns with both the generic PHY driver and Linux MSCC PHY driver
implementations.

The i.MX91 SoC reuses the ENET FEC from i.MX93. Add all required driver
checks to make it work also on the i.MX91 based platforms.

mdio is a child node of the switch, so to get switch base address
we need to lookup for a parent node

Commit d2145a89bcf6 ("net: airoha: bind MDIO controller on Ethernet load")
uses "airoha,en7581-switch" dts node for finding MDIO childs. This is wrong
for EN7523 SoC. The correct node name should be used instead.

refers to non-present CONFIG_MDIO_MT7531 and non-present "mt7531-mdio"

Multicast and Broadcast Queue Enable and Promiscuous Mode Enable bits
are currently written to "unused" registers using magic values.

Define more of the "unused" MAC regs based on information in the
DesignWare Cores Ethernet Quality-of-Service databook.
