[PATCH net-next 3/6] tg3: Fix 57765 EEE support

["Matt Carlson" <mcarlson@broadcom.com>]

EEE support in the 57765 internal phy will not enable after a phy reset
unless it sees that EEE is supported in the MAC.  This patch moves the
code that programs the CPMU EEE registers to a place before the phy
reset.
