net: lan743x: add RMII strap status detection for PCI11x1x

Browse source

Extend pci11x1x_strap_get_status() to read the RMII strap bits from
the STRAP_READ register. The is_rmii_en flag is initialized to
false and updated based on the hardware strap only if SGMII is not
already enabled. This ensures correct interface identification during
adapter initialization.

Update the netif_dbg() to report the selected interface as SGMII,
RMII, or RGMII.
