The parameter offset is an unsigned, so it makes no sense to compare
it for >= 0. Fix the compiler warning regarding this by removing this
comparison.
As the macro GPIO_OFFSET_VALID is only used at this single place, simplify
the code by dropping the macro completely and dropping the invert, too.
No functional change.

This fixes error checking in the function device_pca957x_init
to properly check and return error code values from the calls
to the function pca953x_write_regs if they fail as to properly
signal callers when a error occurs due a failure when writing
registers for this gpio based device.

The state container of the Zynq GPIO driver is sometimes
extracted from the gpio_chip exploiting the fact that offsetof()
the struct gpio_chip inside the struct zynq_gpio is 0, so
the container_of() is in practice a noop. However if a member
is added to struct zynq_gpio in front of struct gpio_chip,
things will break. Using proper container_of() avoids this
problem.
Semantically this is a noop, the compiler will optimize it away,
but syntactically it makes me happier.
Also replace some explicit container_of() calls with the helper
function.

The code in pinctrl-imx.c only works correctly if in the
imx_pinctrl_soc_info passed to imx_pinctrl_probe we have:
info->pins[i].number = i
conf_reg(info->pins[i]) = 4 * i
(which conf_reg(pin) being the offset of the pin's configuration
register).
When the imx25 specific part was introduced in b4a87c9b96 ("pinctrl:
pinctrl-imx: add imx25 pinctrl driver") we had:
info->pins[i].number = i + 1
conf_reg(info->pins[i]) = 4 * i
. Commit 34027ca2bb ("pinctrl: imx25: fix numbering for pins") tried
to fix that but made the situation:
info->pins[i-1].number = i
conf_reg(info->pins[i-1]) = 4 * i
which is hardly better but fixed the error seen back then.
So insert another reserved entry in the array to finally yield:
info->pins[i].number = i
conf_reg(info->pins[i]) = 4 * i

The comment for PG14 mux setting 3 already correctly states that this
muxes PG13 to pwm1, but the text ascociated with it said uart3, fix this.
Note that we use "pwm" rather then "pwm1" to be consistent with pwm0
where the mux setting is also simply called "pwm" and to be consistent
with sun4i/sun7i which do the same.
