From: jinghua <jinghua@marvell.com>
This patch introduces a producer of MARVELL_BOARD_DESC_PROTOCOL, which
gets SoC description from ArmadaSoCDescLib, then based on dsc file,
provide only enabled hardware module controllers for the consumers,
which are typically controllers' drivers. Thanks to that
there is a separation between obtaining the platform description and
the drivers. A first example of the board description callback
is information about UTMI controllers and type.
