Add one Kconfig option for each driver. This will allow to better control which

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.

We previously had an evergrowing (and exhaustive) list of the pins that could
be used on any Allwinner SoCs. These defines were then used by each pinctrl
driver to declare the list of functions for this pin. Since it's pretty much
all boilerplate, we can remove it just by a single macro.

The pins description structure were declared as const, but the of_device_id

The fsafe value in the pingroup data tables is only used to implement
tegra_pinctrl_disable(). The only reason this function is called is when
dynamically switching between pinmux states, i.e. when disabling the old
state before programming the new state. It's simpler to have the new
target state define the expected value of each pin (and all current DTs
do that). This also gives more flexibility, since it allows individual
boards explicit control over the "inactive" mux function for each pin,
rather than requiring it to be an SoC-specific value. Assuming this, we
can get rid of the fsafe value from the driver completely, thus saving
some more space in the driver tables.
While re-writing the content of tegra124_pingroups[], fix the indentation
to use a TAB instead of spaces.

Any SoC which supports the einput, odrain, lock, ioreset, or rcv_sel
options has the relevant HW register fields in the same register as the
mux function selection. Similarly, the drvtype option is always in the
drive register, if it is supported at all. Hence, we don't need to have
struct *_reg fields in the pin group table to define which register and
bank to use for those options. Delete this to save space in the driver's
data tables.
However, many of those options are not supported on all SoCs, or not
supported on some pingroups. We need a way to detect when they are
supported. Previously, this was indicated by setting the struct *_reg
field to -1. With the struct *_reg fields removed, we use the struct
*_bit fields for this purpose instead. The struct *_bit fields need to
be expanded from 5 to 6 bits in order to store a value outside the valid
HW bit range of 0..31.
Even without removing the struct *_reg fields, we still need to add code
to validate the struct *_bit fields, since some struct *_bit fields were
already being set to -1, without an option-specific struct *_reg field to
"guard" them. In other words, before this change, the pinmux driver might
allow some unsupported options to be written to HW.
