This patch adds the necessay intelligence to properly compute the value
of 'old' and 'head' when operating in snapshot mode. That way we can get
the latest information in the AUX buffer and be compatible with the
generic AUX ring buffer mechanic.

So far we have reused the name of the "platform" device for
the CoreSight device. But this is not very intuitive when
we move to ACPI. Also, the ACPI device names have ":" in them
(e.g, ARMHC97C:01), which the perf tool doesn't like very much.
This patch introduces a generic naming scheme, givin more intuitive
names for the devices that appear on the CoreSight bus.
The names follow the pattern "prefix" followed by "index" (e.g, etm5).
We maintain a list of allocated devices per "prefix" to make sure
we don't allocate a new name when it is reprobed (e.g, due to
unsatisifed device dependencies). So, we maintain the list
of "fwnodes" of the parent devices to allocate a consistent name.
All devices except the ETMs get an index allocated in the order
of probing. ETMs get an index based on the CPU they are attached to.
TMC devices are named using "tmc_etf", "tmc_etb", and "tmc_etr"
prefixes depending on the configuration of the device.
The replicators and funnels are not classified as dynamic/static
anymore. One could easily figure that out by checking the presence
of "mgmt" registers under sysfs.

We rely on the device names to find a CoreSight device on the
coresight bus. The device name however is obtained from the platform,
which is bound to the real platform/amba device. As we are about
to use different naming scheme for the coresight devices, we can't
rely on the platform device name to find the corresponding
coresight device. Instead we use the platform agnostic
"fwnode handle" of the parent device to find the devices.
We also reuse the same fwnode as the parent for the Coresight
device we create.

We are about to introduce methods to clean up the platform data
as we switch to tracking the device reference from "name" to "fwnode
handles" for device connections. This requires us to drop the fwnode
handle references when the data is no longer required - i.e, when
the device probe fails or the device gets unregistered.
In order to consolidate the invocation of the cleanup, we delay the
platform probing to the very last minute, possibly before invoking
the coresight_register. Then, we leave the coresight core code to
do the clean up. i.e, if the coresight_register fails, it takes
care of freeing the data. Otherwise, coresight_unregister will
do the necessary operations.

When a device is unregistered, we remove all connection
references to it, by searching the connection records of
all devices in the coresight bus, via coresight_remove_conns.
We could avoid searching if this device doesn't have an input
port (e.g, a source). Also document the purpose of the function.

This patch avoids setting the truncated flag when operating in snapshot
mode since the trace buffer is expected to be truncated and discontinuous
from one snapshot to another. Moreover when the truncated flag is set
the perf core stops enabling the event, waiting for user space to consume
the data. In snapshot mode this is clearly not what we want since it
results in stale data.

Pull powerpc fixes from Michael Ellerman:
"One fix going back to stable, for a bug on 32-bit introduced when we
added support for THREAD_INFO_IN_TASK.
A fix for a typo in a recent rework of our hugetlb code that leads to
crashes on 64-bit when using hugetlbfs with a 4K PAGE_SIZE.
Two fixes for our recent rework of the address layout on 64-bit hash
CPUs, both only triggered when userspace tries to access addresses
outside the user or kernel address ranges.
Finally a fix for a recently introduced double free in an error path
in our cacheinfo code.
Thanks to: Aneesh Kumar K.V, Christophe Leroy, Sachin Sant, Tobin C.
