ARM: mvebu: returns ll_get_cpuid() to ll_get_coherency_cpumask()

In the refactoring of the coherency fabric assembly code, a function
called ll_get_cpuid() was created to factorize common logic between
functions adding CPU to the SMP coherency group, enabling and
disabling the coherency.

However, the name of the function is highly misleading: ll_get_cpuid()
makes one think tat it returns the ID of the CPU, i.e 0 for CPU0, 1
for CPU1, etc. In fact, this is not at all what this function returns:
it returns a CPU mask for the current CPU, usable for the coherency
fabric configuration and control registers.

Therefore this commit renames this function to
ll_get_coherency_cpumask(), and adds additional comments on top of the
function to explain in more details what it does, and also how the
endianess issue is handled.

strongly-ordered (note: MT_UNCACHED is strongly-ordered), and by
removing the outer cache sync done in software. This is implemented in

 * Registering a custom arch_ioremap_caller function that allows to
   make sure PCI memory regions are mapped MT_UNCACHED.

 * Adding at runtime the 'arm,io-coherent' property to the PL310 cache

ARM: OMAP2+: Remove suspend_set_ops from common pm late init

In omap2_common_pm_late_init suspend_set_ops was called to set common
suspend handling functions for all omap platforms. This created two
problems. First, these suspend ops were being set for all platforms,
regardless of whether or not suspend support has been integrated so in
the case of AM33XX, suspend to mem was presented as available but
failed every time. Second, some platforms will need to define a
completely separate set of suspend ops, such as AM33XX, due to
differences from previous omap platforms so there is no need to
always set the common omap ops.

This patch moves the suspend_set_ops call from omap2_common_pm_late_init
into a separate function that then gets called in the omap*_pm_init
functions for each platform.

ARM: mvebu: use hardware I/O coherency also for PCI devices

Since the beginning of the introduction of hardware I/O coherency
support for Armada 370 and Armada XP, the special DMA operations
should have applied to all DMA capable devices. Unfortunately, while
the original code properly took into account platform devices, it
didn't take into account PCI devices, which can also be DMA masters.

This commit fixes that by registering a bus notifier on pci_bus_type,
to register our custom DMA operations, like is already done for
platform devices. While doing this, we also rename
mvebu_hwcc_platform_notifier() to mvebu_hwcc_notifier() and
mvebu_hwcc_platform_nb to mvebu_hwcc_nb because they are no longer
specific to platform devices.
