[PATCH net-next v3 1/5] net: lan743x: rename is_sgmii_en to is_pcs_en

[Thangaraj Samynathan <thangaraj.s@microchip.com>]

The flag is_sgmii_en indicates whether the PCS interface is enabled.
However, the name implies that the interface is strictly SGMII, which is
misleading.

Rename the variable to is_pcs_en to better reflect that the flag
represents the PCS enable state rather than a specific interface mode.
Update all references and logs accordingly (but keep device registers
unchanged to match its documentation).

No functional change intended.
