USART doc starting p572, registers p621.

After looking at the datasheet, I don't see any reason why one of the
two drivers can't be selected using different compatible strings.

Because there is only one IP and we don't use the device tree to selecet
linux specific drivers.

If you are not happy having that in MFD, I guess we can move it out
somewhere else.
