tg3 / broadcom: Refine AC131 APD support
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.
