[yocto] [meta-raspberrypi][PATCH] rpi-config: waveshare screen support

[Trevor Woerner]

I see what happened... knowing that I needed those lines set, my
bbappend didn't have the "if" line, it simply applied the lines
without the check. The check was added when pushing upstream just in
case somebody didn't want those lines in their config :-) I should
have tested more extensively after adding the line.

Sorry!
