[PATCH] spi/pl022: get rid of chipinfo dev pointer

[Linus Walleij]

What is the dev pointer doing inside the platform data anyway.
We have another pointer to the actual device at hand, use that.

Note: this is based off Kevin Wells patch for using the proper
modebits since I expect that to go in first. If you want this to
go before that patch, tell me and we both have to rebase.
