net: dsa/mv88e6xxx: add reg read and write debug
This commit adds debug messages for the generic mv88e6xxx read and write
routines. The output is similar to this:
mdio-gpio mdio-gpio.0: <- addr: 0x1b reg: 0x05 val: 0x4000
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x07 val: 0x3113
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x08 val: 0x0330
mdio-gpio mdio-gpio.0: -> addr: 0x1b reg: 0x09 val: 0x0000
This is convenient to dynamically debug operations through debugfs with:
echo file mv88e6xxx.c +p > <debugfs>/dynamic_debug/control
