media: update/fix my e-mail on some places

There are two places pointing to an unexisting "[email protected]"
email. I never had such email, so, I'm unsure how it ends there.
Anyway, it is plain wrong.

While here, use my canonical e-mail on a bunch of places that
are pointing to another e-mail. The idea is that, from now on,
all places will be pointing to the same SMTP server.

[media] rc: change wakeup_protocols to list all protocol variants

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.

In addition, we need to know the specific variant of the protocol.

In short, these changes are made to the wakeup_protocols sysfs entry:
- list all the protocol variants rather than the protocol groups,
e.g. "nec nec-x nec-32" rather than just "nec".
- only allow one protocol variant to be selected rather than multiple
- wakeup_filter can only be set once a protocol has been selected in
wakeup_protocols.

This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

[media] rc: add wakeup_protocols sysfs file

Add a wakeup_protocols sysfs file which controls the new
rc_dev::enabled_protocols[RC_FILTER_WAKEUP], which is the mask of
protocols that are used for the wakeup filter.

A new RC driver callback change_wakeup_protocol() is called to change
the wakeup protocol mask.

[media] media: rc: add sysfs scancode filtering interface

Add and document a generic sysfs based scancode filtering interface for
making use of IR data matching hardware to filter out uninteresting
scancodes. Two filters exist, one for normal operation and one for
filtering scancodes which are permitted to wake the system from suspend.

The following files are added to /sys/class/rc/rc?/:
- filter: normal scancode filter value
- filter_mask: normal scancode filter mask
- wakeup_filter: wakeup scancode filter value
- wakeup_filter_mask: wakeup scancode filter mask

A new s_filter() driver callback is added which must arrange for the
specified filter to be applied at the right time. Drivers can convert
the scancode filter into a raw IR data filter, which can be applied
immediately or later (for wake up filters).
