[platforms PATCH 01/25] Marvell/Library: Introduce ArmadaSoCDescLib class

[Marcin Wojtas <mw@semihalf.com>]

From: jinghua <jinghua@marvell.com>

ArmadaSoCDescLib is a per SoC family library, which provides SoC
description, like register base of some hardware module controller,
COMPHY/I2C/NETWORK etc., which right now is hardcoded in MvHwDescLib.h.
There will be a new protocol, which gets SoC description from this
library, and provides board description based on enable/disable
values of each hardware module controller in dsc file.

As a first example implement obtaining UTMI controllers information.
Remaining interfaces will be added in follow-up commits.
This patch introduces new library callback (ArmadaSoCDescUtmiGet ()),
which dynamically allocates and fills MV_SOC_UTMI_DESC structure,
SoC description of UTMI PHYs. A new PCD is introduced (PcdMaxCpCount)
which stores maximal amount of CP110 blocks in the SoC family.
