This SoC contains a pinctrl with a new register layout. Use the variant
parameter to set the right register offsets. This pinctrl also increases
the number of functions per pin from 8 to 16, taking advantage of all 4
bits in the mux config field (so far, only functions 0-8 and 14-15 are
used). This increases the maximum possible number of functions.

Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the
pinctrl registers. This new layout widens the drive level field, which
affects the pull register offset and the overall bank size.
In order to support multiple register layouts, some of the layout
parameters need to be set based on the pinctrl variant. This requires
passing the pinctrl struct pointer to the register/offset calculation
functions.

Starting with the D1/D1s/T113 SoC, Allwinner changed the layout of the
pinctrl registers. This new layout widens the drive level field, which
affects the pull register offset and the overall bank size.
As a first step to support this, combine the register and offset
calculation functions, and refactor the math to depend on one constant
for field widths instead of three. This minimizes the code size impact
of making some of the factors dynamic.
While rewriting these functions, move them to the implementation file,
since that is the only file where they are used. And make the comment
more generic, without mentioning specific offsets/sizes.
The callers are updated to expect a shifted mask, and to use consistent
terminology (reg/shift/mask/val).

H616 and newer SoCs feature a 2.5V I/O bias mode in addition to the
1.8V and 3.3V modes. This mode is entered by selecting the 3.3V level
and disabling the "withstand function".
H616 supports this capability on its main PIO only. A100 supports this
