media: rc: keymaps: add missing MODULE_DESCRIPTION to keymaps

When building the modules 'modpost' warns about missing MODULE_DESCRIPTION.

Since almost none of the rc keymap modules have this, it produces a lot of
warnings.

As a first step to fixing all media modules, add this line to all keymaps.
The description should be a human-readable string describing the remote
or the remote controller that the keymap can be used with.

Note that keymaps/rc-cec.c is actually compiled into the rc-core, so that
is the sole keymap source that didn't need this.

media: rc: Prefer KEY_NUMERIC_* for number buttons on remotes

Prefer KEY_NUMERIC_* for number buttons on remotes. Now all the remotes
use KEY_NUMERIC_[0-9] for the number buttons rather than keys that
could be affected by modifiers (Caps-Lock, or Num-Lock) or regional
keymaps.

Created using:
sed -i 's/KEY_\([0-9]\) /KEY_NUMERIC_\1 /' *.c
sed -i 's/KEY_\([0-9]\)}/KEY_NUMERIC_\1}/' *.c
sed -i 's/``KEY_\([0-9]\)/``KEY_NUMERIC_\1/' Documentation/media/uapi/rc/rc-tables.rst

media: rc: rename RC_TYPE_* to RC_PROTO_* and RC_BIT_* to RC_PROTO_BIT_*

RC_TYPE is confusing and it's just the protocol. So rename it.

[media] media: Drop FSF's postal address from the source code files

Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.

The patch has been created with the following command without manual edits:

git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
$a=join("", <F>);
$a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m
&& $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m;
close(F);
open(F, "> $ENV{i}");
print F $a;
close(F);'; done

drivers/media: Add module.h to all files using it implicitly

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore. Make sure the modular drivers in clocksource
are actually calling out for <module.h> explicitly in advance.

[media] technisat-usb2: added driver for Technisat's USB2.0 DVB-S/S2 receiver

This patch is adding support for Technisat's new USB2.0 DVB-S/S2 receiver
device. The development was sponsored by Technisat.

The Green led is toggle depending on the frontend-state. The Red LED is turned
on all the time.

The MAC address reading from the EEPROM along with the
LRC-method to check whether its valid.

Support for the IR-receiver of the Technisat USB2 box. The keys of
small, black remote-control are built-in, repeated key behaviour are
simulated.

The i2c-mutex of the dvb-usb-structure is used as a general mutex for
USB requests, as there are 3 threads racing for atomic requests
consisting of multiple usb-requests.

A module option is there which disables the toggling of LEDs by the
driver on certain triggers. Useful when being used in a "dark"
environment.
