Old pinctrl drivers will need to disable strict mode for various reasons,
among which:
- Some DT will still have a pinctrl group for each GPIO used, which will
be rejected by pin_request. While we could remove those nodes, we still
have to deal with old DTs.
- Some GPIOs on these boards need to have their pin configuration changed
(for bias or current), and there's no clear migration path
Let's disable the strict mode on those SoCs so that there's no breakage.

The I2C pin functions in R_PIO used to be named "s_twi".
As we usually use the name "i2c" instead of "twi" in the mainline
kernel, change these names to "s_i2c" for consistency.
The "s_twi" functions are not yet referenced by any device trees in
mainline kernel so I think it's safe to change the name.

H3 has additional PIO controller similar to what we can find on A23.
It's a 12 pin port, described in H3 Datasheet rev 1.1, pages 345-350.
