====================
macb: add zynqmp SGMII dynamic configuration support

This patchset add firmware and driver support to do SD/GEM dynamic
configuration. In traditional flow GEM secure space configuration
is done by FSBL. However in specific usescases like dynamic designs
where GEM is not enabled in base vivado design, FSBL skips GEM
initialization and we need a mechanism to configure GEM secure space
in linux space at runtime.
