Fix the following warning when the driver is compiled as built-in:

      warning: unused import: `DeviceId`
      --> drivers/net/phy/qt2025.rs:18:5
      |
   18 |     DeviceId, Driver,
      |     ^^^^^^^^
      |
      = note: `#[warn(unused_imports)]` on by default

device_table in module_phy_driver macro is defined only when the
driver is built as a module. Use phy::DeviceId in the macro instead of
importing `DeviceId` since `phy` is always used.
