For some reason I thought GPIOLIB handles translation from GPIO ranges
to pinctrl pins but it turns out not to be the case. This means that
when GPIOs operations are performed for a pin controller having a custom
GPIO base such as Cannon Lake and Ice Lake incorrect pin number gets
used internally.
Fix this in the same way we did for lock/unlock IRQ operations and
translate the GPIO number to pin before using it.

Because the pincrl-mtk-common.c is an implementation for per-pin binding,
its pin descriptor includes more information than pinctrl-mtk-common-v2
so far can support. So, we complement these data before writing a driver
using pincrl-mtk-common-v2.c for per-pin binding. By the way, the size of
struct mtk_pin_desc would be larger than struct pinctrl_pin_desc can hold,
so it's necessary to have a copy before the pins information is being
registered into the core.

This patch adds members sz_reg fixed in struct mtk_pin_field_calc
- The 'fixed' is used to represent the consecutive pins share the same
bits within the same register with the 1st pin so that it can largely
reduce the entry size a bit.
- The 'sz_reg' is used to indicate the range of bits we use in a register
that may vary by SoC
The above changes make the code more generic and this is useful as there
might be other existing or future chips all use the same logic to access
their register set and then being a little more abstract could help in the
long run.

Irregular register arrangement and distinct logic access from various
MediaTek SoCs would cause pinctrl-mtk-common to bloat and really hard to
maintain in the future so that the patch creates pinctrl-mtk-common-v2
based on the core of mt7622-pinctrl.
The goals pinctrl-mtk-common-v2 want to achieve are to hopefully support
all of MediaTek SoCs, and two kinds of dt-bindings being supported,
Linux generic pinctrl dt-binding mt7622 supports and MediaTek per-pin
dt-binding the other SoCs support the MT8183 and MT6765 incline to make
use of.
The patch starts to refactor MT7622 pinctrl driver first with splitting
out these portable ways from there such as table-based register operation
and drive strength control that is common in both kinds of driver.
