This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

interconnect changes for 5.13

These are the interconnect changes for the 5.13-rc1 merge window
with the highlights being drivers for two new platforms.

Driver changes:
- New driver for SM8350 platforms.
- New driver for SDM660 platforms.

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.

Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

This patch series adds the SDM660 interconnect provider driver in
order to stop some timeouts and achieve some decent performance by
avoiding to be NoC limited.
It's also providing some power consumption improvement, but I have
only measured that as less heat, which is quite important when
working on thermally constrained devices like smartphones.

Please note that this driver's yaml binding is referring to a MMCC
clock, so this series does depend on the SDM660 MMCC driver that I
have sent separately.
The multimedia clock is required only for the Multimedia NoC (mnoc).

This patch series has been tested against the following devices:
 - Sony Xperia XA2 Ultra (SDM630 Nile Discovery)
 - Sony Xperia 10        (SDM630 Ganges Kirin)
 - Sony Xperia 10 Plus   (SDM636 Ganges Mermaid)

There is a link between the GEM NoC and C NoC nodes, which is currently
missing from the topology. Let's add it to allow consumers request paths
that use this link.

For creating an array with the members for each NoC, we should be using
a local indexes, as otherwise unnecessary large arrays would be created.
Using an incorrect indexes will also result error for the consumers when
they try to find a valid path between the endpoints. Let's fix this and
use the correct ids.
