media: ddbridge: bump ddbridge code to version 0.9.29

This huge patch bumps the ddbridge driver to version 0.9.29. Compared to
the vendor driver package, DD OctoNET including GTL link support, and all
DVB-C Modulator card support has been removed since this requires large
changes to the underlying DVB core API, which should eventually be done
separately, and, after that, the functionality/device support can be added
back rather easy.

While the diff is rather large, the bump is mostly a big refactor of all
data structures. Yet, the MSI support (message signaled interrupts) is
greatly improved, also all currently available CI single/duo bridge cards
are fully supported.

More changes compared to the upstream driver:
 - the DDB_USE_WORKER flag/define was removed, kernel worker functionality
   will be used.
 - coding style is properly fixed (zero complaints from checkpatch)
 - all (not much though) CamelCase has been fixed to kernel_case
 - (private) IOCTLs temporarily removed (which are mainly used to provide
   rarely-used FPGA update functionality)

Great care has been taken to keep all previous changes and fixes (e.g.
kernel logging via dev_*(), pointer annotations and such) intact.

Permission to reuse and mainline the driver code was formally granted by

media: ddbridge: split code into multiple files

As of 0.9.9b, the ddbridge code has been split from one single file
(ddbridge-core.c) into multiple files, with the purpose of taking care of
different topics, and to be able to reuse code in different kernel modules
(ddbridge.ko and octonet.ko). This applies the same code split, with a
notable difference:

In the vendor package, the split was done by moving all code parts into
separate files, and in the "main" code files (ddbridge.c and octonet.c),
a simple "#include ddbridge-core.c" was done.

In this patch, the same split (codewise) is done, but all resulting .c/.o
files will be handled by the makefile, with proper prototyping of all
shared functions done in ddbridge.h. To avoid conflicts wrt the global
space, the I2C functions and necessary prototypes for ddbridge-i2c.c are
moved into ddbridge-i2c.h, which is to be included wherever required.

media: v4l2-compat-ioctl32: Fix timespec conversion

Certain syscalls like recvmmsg support 64 bit timespec values for the
X32 ABI. The helper function compat_put_timespec converts a timespec
value to a 32 bit or 64 bit value depending on what ABI is used. The
v4l2 compat layer, however, is not designed to support 64 bit timespec
values and always uses 32 bit values. Hence, compat_put_timespec must
not be used.

Without this patch, user space will be provided with bad timestamp
values from the VIDIOC_DQEVENT ioctl. Also, fields of the struct
v4l2_event32 that come immediately after timestamp get overwritten,
namely the field named id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.
