[PATCH net-next v2 2/3] phy: Add defines for standardized PHY generic counters

[Oleksij Rempel <o.rempel@pengutronix.de>]

Introduce a set of defines for generic PHY-specific counters.
These defines provide standardized names for commonly
tracked statistics across different PHY drivers, ensuring consistency in
how these metrics are reported:

- `PHY_TX_PKT_COUNT`: Transmit packet count.
- `PHY_RX_PKT_COUNT`: Receive packet count.
- `PHY_TX_ERR_COUNT`: Transmit error count.
- `PHY_RX_ERR_COUNT`: Receive error count.
