The latest NetsecDxe requires issueing phy reset at the
last stage of initialization to safely exit loopback mode.
However, as a result, it takes a couple of seconds for link state
to get stable, which could cause auto-chosen pxeboot to fail
due to MediaPresent check error.
This patch adds link state check with 5s timeout in NetsecDxe
initialization. The timeout value can be adjustable via
configuration file.
