vendorsetup.sh: Add p5 and p5wifi (Samsung Galaxy Tab 8.9 P7300(3G+wifi) and P7310(wifi-only))

Repos that needs to be forked:
https://github.com/kalltkaffe/android_device_samsung_p5-common
https://github.com/kalltkaffe/android_device_samsung_p5
https://github.com/kalltkaffe/android_device_samsung_p5wifi

Proprietary files:
https://github.com/kalltkaffe/android_vendor_samsung_p5
https://github.com/kalltkaffe/android_vendor_samsung_p5wifi

Known issues:
- Camera is not working.
- Compass is 90 degrees wrong.
- Rotation animation "blanks out" before it starts.
- Voice calls (p5 version) isn't working although some report recieving calls work while outgoing calls is not.
- HDMI output is rotated 90 degrees.

Some more info:
Most of this is based upon the p4/p4wifi repos as it shares a lot with the p4 and I've forked pershoots p4 kernel and modified it to work with the p5.
It's very stable and can be used as a daily driver, the biggest limitation is the lack of working cameras (imho).
