The use of two separate structs (lirc_dev aka lirc_driver and irctl) makes
it much harder to follow the proper lifetime of the various structs and
necessitates hacks such as keeping a copy of struct lirc_dev inside
struct irctl.
Merging the two structs means that lirc_dev can properly manage the
lifetime of the resulting struct and simplifies the code at the same time.

Introduce two new functions so that the API for lirc_dev matches that
of the rc-core and input subsystems.
This means that lirc_dev structs are managed using the usual four
functions:
lirc_allocate_device
lirc_free_device
lirc_register_device
lirc_unregister_device
The functions are pretty simplistic at this point, later patches will put
more flesh on the bones of both.

Use the irctl mutex for all device operations and only use lirc_dev_lock
to protect the irctls array. Also, make sure that the device is alive
early in each fops function before doing anything else.
Since this patch touches nearly every line where the irctl mutex is
taken/released, it also renames the mutex at the same time (the name
irctl_lock will be misleading once struct irctl goes away in later
patches).

Make setting chunk_size and buffer_size mandatory for drivers which
expect lirc_dev to allocate the lirc_buffer (i.e. ir-lirc-codec) and
don't set them in lirc-zilog (which creates its own buffer).

same information is already available from struct lirc_buffer).

By making better use of file->private_data in lirc_dev we can avoid
digging around in the irctls[] array, thereby simplifying the code.
External drivers need to use lirc_get_pdata() instead of mucking around
in file->private_data.
The newly introduced lirc_init_pdata() function isn't very elegant, but
it's a stopgap measure which can be removed once lirc_zilog is converted
to rc-core.

All users of lirc_register_driver() uses dynamic minor allocation,

The help text should be indented by at least two spaces after the
'help' separator. This is both good practice and the media_build system
for building media drivers makes this assumption.
I went through all Kconfigs under drivers/media and fixed any bad help
sections. This makes it conform to the common practice and should fix
problems with 'make menuconfig' when using media_build. This is due to
a "WARNING" message that media_build can insert in the Kconfig and that
assumes the help text is indented by at least two spaces. If not, then the
Kconfig becomes invalid and 'make menuconfig' fails.

In the distant past the adv7604 driver used private controls. In order
to access them the v4l-subdevX nodes were needed. Later the is_private
tag was removed in the adv7604 driver and the need for v4l-subdevX
device nodes disappeared.
Remove the creation of those device nodes from this driver.
Note: the cobalt card is only used inside Cisco and we never actually
used the v4l-subdevX nodes for anything. So this API change can be done
safely without breaking anything.
