												ARM: 7298/1: realview: fix mapping of MPCore private memory region
Since commit 0536bdf33faf (ARM: move iotable mappings within
the vmalloc region), the RealView PB11MP cannot boot anymore.
This is caused by the way the mappings are described on this
platform (define replaced by hex values for clarity):
{	/* GIC CPU interface mapping */
        .virtual        = IO_ADDRESS(0x1F000100),
        .pfn            = __phys_to_pfn(0x1F000100),
        .length         = SZ_4K,
        .type           = MT_DEVICE,
}, {	/* GIC distributor mapping */
        .virtual        = IO_ADDRESS(0x1F001000),
        .pfn            = __phys_to_pfn(0x1F001000),
        .length         = SZ_4K,
        .type           = MT_DEVICE,
}
The first mapping ends up reserving two pages, and clashes with
the second one, which triggers a BUG_ON in vm_area_add_early().
In order to solve this problem, treat the MPCore private memory
region (containing the SCU, the GIC and the TWD) as a single region,
as described in the TRM:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html
The EB11MP is converted the same way, even if it manages to avoid
the problem.
Tested on both PB11MP and EB11MP.
