[PATCH] net: phy: Fix rgmii-id phy reset timeout issue

[Michal Simek]

From: T Karthik Reddy <t.karthik.reddy at xilinx.com>

While creating a phy device using phy_device_create(), we need to
provide a valid phyaddr instead of 0 causing phy address being
registered as 0 with mdio bus and shows mdio phy list as below

ZynqMP>  mdio list
eth0:
0 - TI DP83867 <--> ethernet at ff0b0000
eth1:
0 - TI DP83867 <--> ethernet at ff0c0000

Also PHY soft reset is being requested on 0 instead of valid
address causing "PHY reset timed out" error.

So add phyaddr argument to phy_connect_phy_id() and to its prototype
to create phy device with valid phyaddress.

Fixes: a744a284e354 ("net: phy: Add support for ethernet-phy-id with gpio reset")
