We must unlock the mutex *after* the `out` label or we'd trigger a

Ensure only valid pins are configured by validating pin mappings before
setting the mux function.
Rename rzg2l_validate_gpio_pin() to rzg2l_validate_pin() to reflect its
broader purpose validating both GPIO pins and muxed pins. This helps
avoid invalid configurations.

As part of a wider cleanup trying to get rid of OF specific APIs, an
incorrect (and partially unrelated) cleanup was introduced.
The goal was to replace a device_for_each_chil_node() loop including an
additional condition inside by a macro doing both the loop and the
check on a single line.
The snippet:
device_for_each_child_node(dev, child)
if (fwnode_property_present(child, "gpio-controller"))
continue;
was replaced by:
for_each_gpiochip_node(dev, child)
which expands into:
device_for_each_child_node(dev, child)
for_each_if(fwnode_property_present(child, "gpio-controller"))
This change is actually doing the opposite of what was initially
expected, breaking the probe of this driver, breaking at the same time
the whole boot of Nuvoton platforms (no more console, the kernel WARN()).
Revert these two changes to roll back to the correct behavior.

On some platforms, the UFS-reset pin has no interrupt logic in TLMM but
is nevertheless registered as a GPIO in the kernel. This enables the
user-space to trigger a BUG() in the pinctrl-msm driver by running, for
example: `gpiomon -c 0 113` on RB2.
The exact culprit is requesting pins whose intr_detection_width setting
is not 1 or 2 for interrupts. This hits a BUG() in
msm_gpio_irq_set_type(). Potentially crashing the kernel due to an
invalid request from user-space is not optimal, so let's go through the
pins and mark those that would fail the check as invalid for the irq chip
as we should not even register them as available irqs.
This function can be extended if we determine that there are more
corner-cases like this.

Fill struct irq_chip::irq_set_affinity to use the default helper
function.

The commit acaa037970f6 ("pinctrl: stm32: Implement .get_direction
gpio_chip callback") exported the function stm32_pmx_get_mode()
and the struct stm32_gpio_bank, but these were never used outside
the file that defines them.
Declare the function as static, drop it from the include file and
drop also the struct, not anymore visible outside the file.

The RP1 is an MFD supporting a gpio controller and /pinmux/pinctrl.
Add minimum support for the gpio only portion. The driver is in
pinctrl folder since upcoming patches will add the pinmux/pinctrl
support where the gpio part can be seen as an addition.

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.
