net: dp83822: Print the SOR1 strap status

Browse Source 
During the bring-up of the Ethernet PHY, it is very useful to
see the bootstrap status information, as it can help identifying
hardware bootstrap mistakes.

Allow printing the SOR1 register, which contains the strap status
to ease the bring-up.
