Problem is that the Linux implementation sucks :/

At least on i.MX this driver is a pain to use. It needs more quirks than
fit into a 32bit variable and still the i.MX port needs driver logic
in the register accessor functions. Maybe i.MX is the worst of all
implementations, but I'm not considering using the Linux driver for
i.MX on barebox.
If other SoCs work better with the Linux driver we can still merge it
though.
