net: phy: Constify struct mdio_device_id
'struct mdio_device_id' is not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
27014 12792 0 39806 9b7e drivers/net/phy/broadcom.o
After:
=====
text data bss dec hex filename
