Marvell/Library: UtmiPhyLib: Switch to use MARVELL_BOARD_DESC protocol

UTMI driver used to get Armada7k8k UTMI controller description from
hardcoded values stored in the header file MvHwDescLib.h.
As a result it is very hard to support other Armada SoC families
with this driver.

This patch updates the driver to get UTMI controller description from
newly introduced MARVELL_BOARD_DESC protocol, and removes the dependency
on the hardcoded structures. Use the protocol and pass information to
further to the library init routine.
