Unclear of the pinout for the LCD->RPi project

[nageebt]

I'm trying to reproduce your RPi clock project with an old Gameboy LCD but am unclear on what the pinouts are.

From a comment in gblcd.c it appears that all the control signals are being fed through the Red pins but I'm not 100% certain if I'm reading the code properly. It's also unclear which pins the DATA1 & DATA0 are using (Red 6 and 7?)

If you could clarify these details, I would be happy to document your code and submit a PR.

Use of RED or BLUE depends in which mode you are using your frame buffer. Mine happens to be in BGRA. So those comments are not quite correct - in my case.

I have added some clarification into readme. I hope it makes things clearer now.
