Offset on meson pinctrl and gpios is something that was carried from the
vendor driver, where there is a weird link between the 2
controllers. Since these 2 controllers are independent, this offset adds
an unnecessary complexity.

This patch remove this manually set offset and rely on pinctrl to figure
out the gpio base offset

Thx Linus.

Just to be sure, did you remember to squash patch 1 to 5 together ?

I know it is a bit unusual but, as explained earlier, those patches were only
split to ease the review. Keeping the change split would break bisect.
