[PATCH v3 0/5] Consolidate lan9118 phy implementations

[Bernhard Beschow <shentey@gmail.com>]

hw/net/imx_fec and hw/net/lan9118 implement the same Ethernet PHY with similar
but not quite the same code. This series consolidates the implementations into
one to fix code duplication. It then continues to make the code more readable by
reusing some existing constants.

Having a dedicated module for the PHY allows it to be reused in even further
device models.

Testing done:
* Run my usual sabrelite load and verify that network works.
* Build and run Buildroot's qemu_arm_vexpress_defconfig which includes lan9118
  and check on serial console that IP address gets assigned.

v3:
* Don't add SOFT reset, use device-specific method instead (Peter)
* Reuse MII constants for MII_ANLPAR register which was previously missed
* Fix off-by-one error in MII_ANLPAR register which prevented MII constants to
  be reused

v2:
* QOM'ify + mention boards whose migratability will be broken (Peter)

Bernhard Beschow (5):
  hw/net/lan9118: Extract lan9118_phy
  hw/net/lan9118_phy: Reuse in imx_fec and consolidate implementations
  hw/net/lan9118_phy: Fix off-by-one error in MII_ANLPAR register
  hw/net/lan9118_phy: Reuse MII constants
  hw/net/lan9118_phy: Add missing 100 mbps full duplex advertisement
