Additionally, some of this should move to using standard driver models that now
exist. For example qe_ic.{c,h} should possibly look at going into
drivers/irqchip/. gpio.c should be looked to use gpiolib and move into
drivers/gpio. Some of the pinmux that exists in qe.c and ucc.c should look at
the drivers/pinctrl and there is some amount of clk config that I wonder if it
could move the common clk API and drivers/clk.
There will still be some qe_lib specific code, but vastly reduced.
