[tvos] - remove iokit linkage

[Memphiz]

I know linking against IOKit framework was added for a reason. But i can't find any addon in our repo that needs this atm. Also on TVOS IOKit is a private framework which we can't link to.

I already did a binary-addons testbuild on jenkins with this and didn't see any issues.

@wsnipex @Montellese we will need a similar change to the platform repo. As far as i can see it is maintained by Pulse-Eight and @opdenkamp renamed it to platform-p8 which breaks a lot of our addons. I am not sure where to PR this change then.

1. Are we going to fork the pulseeight repo and undo the rename?
2. Are we stuck with the current platform version?
3. Do we need to fix all addons for matching the rename?

Any advice on how i get this change into the platform is welcome.

[opdenkamp]

The breakage was on purpose to allow both the old and new named lib to be used at the same time.

[opdenkamp]

And no undoing of that rename if you want to be in Debian/Ubuntu some day, it was done to keep those guys happy.

[Memphiz]

So the idea is to follow the rename or fork to the commit before the rename? I mean for the kodi project...

[opdenkamp]

For Kodi, which we want to have in Debian based dists too (unless something changed), we should upgrade things to use the new name instead. Because the two can co-exist, it doesn't have to be done in 1 go for everything, but we can update things one by one if needed. But basically, all that needs to be done is change the namespace with a big sed operating and change 2 lines in CMakeLists.txt

[Memphiz]

plus fixing alle the find-platform.cmake scripts in the various addons i think :)

[opdenkamp]

That's the 2 lines changed in CMakeLists.txt that I meant. Just changes the generic name 'platform' into 'p8-platform'.

[opdenkamp]

looks ok to me
