From: Sami <sami.mujawar@arm.com>

When network functionality is not required, the boot process is
impeded by redundant network timeouts. Moreover Juno is a mobile
platform so it makes sense to have an option to disable the
(ethernet) networking support.  We therefore introduce the
DISABLE_NETWORK build option.

By default ArmJunoDxe configures the MAC address. This is redundant
when networking is disabled, so the MAC Address configuration is
removed when the DISABLE_NETWORK build option is defined.
