Modify the functions we use to read information about the topology of
the system (the number of cores, VPs & IOCUs that it contains) in order
to take into account multiple clusters, and provide a new function to
determine the number of clusters in the system.
Users of these functions are modified only such that they continue to
build successfully - having them actually handle multiple clusters is
left to further patches.

With Coherence Manager (CM) 3.5 information about the topology of the
system, which has previously only been available through & accessed from
the CM, is now also provided by the Cluster Power Controller (CPC). This
includes a new CPC_CONFIG register mirroring GCR_CONFIG, and similarly a
new CPC_Cx_CONFIG register mirroring GCR_Cx_CONFIG.
In preparation for adjusting functions such as mips_cm_numcores(), which
have previously only needed to access the CM, to also access the CPC
this patch modifies the way we use the various CPS headers. Rather than
having users include asm/mips-cm.h or asm/mips-cpc.h individually we
instead have users include asm/mips-cps.h which in turn includes
asm/mips-cm.h & asm/mips-cpc.h. This means that users will gain access
to both CM & CPC registers by including one header, and most importantly
it makes asm/mips-cps.h an ideal location for helper functions which
need to access the various components of the CPS.

Remove the Malta-specific CM probe code and instead make use of the
newly added generic CM code.

Boot log says:
pci 0000:00:0a.3: no compatible bridge window for [io 0x1000-0x103f]
pci 0000:00:0a.3: no compatible bridge window for [io 0x1100-0x110f]
The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.
This patch actually reverts the change made by c5de50dada. And with this
fix, log says:
pci 0000:00:0a.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI
pci 0000:00:0a.3: quirk: [io 0x1100-0x110f] claimed by PIIX4 SMB
These things may not be used but as part of platform resources are better
off to be included.
