As we added A20 support to A10 pinctrl driver, now we can delete the
dedicated A20 pinctrl driver, which is duplicated code.

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only. All
drivers get essentially the same change, so they are handled in batch.
Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We do delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

While I was testing irq's on the cubietruck I found a couple of
not working irq pins. Further diving into the problem it opened
up a mess called "manual".
This so called manual (A20 user manual v1.3 dated 2014-10-10) says:
Pin overview:
Page 237: EINT26 is on mux 5.
Page 288: EINT26 is on mux 6.
The manual is so contradicting that further tests had to be made
to see which of the 2 statements where correct.
This patch is based on actual outcome of these tests and not what
the manual says.
Test procedure used:
Connect a 1 pulse per second (GPS) line to the pin.
echo pin### > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio###/direction
echo rising > /sys/class/gpio/gpio###/edge
Check /proc/interrupts if a irq was attached and if irq's where
received.
Hardware used:
Henry Paulissen: Cubietruck
Andere Przywara: BananaPi M1

Pin overview:
Page 233: EINT12 is on pin PC19 mux6.
Page 236: EINT12 is on pin PH12 mux6.
Now, it is a bit strange to have the same IRQ on 2 different pins,
but I guess this could still be possible hardware wise. But then:
Pin registers:
Page 253: EINT12 is *not* on pin PC19.
Page 281: EINT12 is on pin PH12.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

Move the pin description to a driver specific to be.
This is the final step toward retiring pinctrl-sunxi-pins.h that used to define
all the pins for all the Allwinner SoCs in a single header, that would have in
turn result in having these structures in the final binary as many times as the
header was included.
We can finally remove that header, and remove all the driver part of the
pinctrl-sunxi core.
