Platforms/Marvell: Create MppLib

 - Create Mpp Library, which allows to set MPP on board.
 - Create Platforms/Marvell/Marvell.dec file, which holds PCDs' declaration.
 - Export configuration capabilities via PCDs.
 - Prepare porting guide document

Because GetMppPcd has to be adjusted to possible 8 MPP registers,
although unused, additional PcdChip<X>MppSel are added in order to
satisfy preprocessor demands. For the same reason there are MPP
PCDs for all of 4 possible chips.
