tg3 / broadcom: Refine AC131 APD support

Browse Source 
Auto power-down (APD) support is a power-saving feature.  It should be
selectively enabled since it might expose MAC bugs.  This patch changes
the code to enable APD only if the PHY_BRCM_AUTO_PWRDWN_ENABLE flag is
set.  The tg3 driver was changed to set this bit.
