[PATCH 1/4] net: dsa: mv88e6xxx: Allow mv88e6xxx_smi_init() to be used at address 0x1

[Romain Perier]

Currently, the function mv88e6xxx_smi_init() returns -EINVAL if the bit
zero of sw_addr is 0x1. However, on some platforms, ethernet switches
are configured in Multi chip addressing mode and available at MDIO
address 0x1.
