Simon Guinot c59c085731 ARM: don't probe PHY address for LaCie boards
The command miiphy_read(name, 0xEE, 0xEE, (u16 *) &devadr) always
returns 8 for the PHY address. It is the reset value for the PHY
Address Register. Obviously, this default value could be incorrect.
Moreover, as the PHY address is well known, there is no need to
auto-detect it.

Now, the PHY address must given as a parameter to the PHY initialization
function. Additionally this patch also fixes some aesthetic issues.
