add support for Raspberry Pi 4

[jake5253]

Only tested on RPI4B 8GB version using default GPIO pins... but since the only thing really different is the peri_base address, if it worked on rpi1-3, everything should be golden on rpi4.

Recovered my BusPirate woohoo!

Hello,

I just wanted to make exactly the same PR (add rpi4), then I realized this pull request already exists.

But since there was no answer from the PR owner for more than a year, could we close this and I make a new PR for the raspberry pi 4?

My changes are exactly the same, only other wording :)

Hi @MikeDK,

as you can imagine, the project is not really maintained anymore... but if you open a MR I'll look injto it with pleasure!

[MikeDK]

@WallaceIT already done that 😉

https://github.com/WallaceIT/picberry/pull/20

Too bad to hear its not maintained any more as this is a really cool project 👍

[WallaceIT]

Functionality merged in #20 - closing this one.

Thanks to all who contributed!
