This adds a driver for the Tegra124 pinmux, and required
parameterization data for Tegra124.
The driver uses the common Tegra pincontrol driver utility
functions to implement the majority of the driver.
This driver is not compatible with the earlier NVIDIA's SoCs,
hence add new compatibile as "nvidia,tegra124-pinmux".

On non-DT platforms IRQ controllers associated with the GPIOs have a
fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.
Fix this by specifying IRQs associated with GPIOs in IRQ resources,
populated automatically from the device tree. When IRQ resources are
specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.

ops->pin_config_get() is only used in one specific path that will only be taken
for generic pinconf drivers (ops->is_generic == true) when dumping the pinconf
by using debugfs.
By removing the check in pinconf_check_ops(), let's stop pressuring people to
write a pin_config_get() function that will never be used and so will probably
never be tested.
Removing the check in pinconf_pins_show() allows driver to not implement
pin_config_get() but still get a dump of the pinconf in debugfs by implementing
pin_config_dbg_show().
Finally, not implementing pin_config_get() now results in returning -ENOTSUPP
instead of -EINVAL. While this doesn't have any real impact for now, this feels
more right.

ChangeLog v2->v3:
- Total failure with older approaches: what we need to do is
have the *SoC subdriver* depend on OF and OF_IRQ. This is
because the placeholder bool PINCTRL_MSM cannot cascade its
dependencies when a subdriver selects it, Kconfig is smart
but not that smart.
ChangeLog v1->v2:
- OK so "depends on OF" did not work here let's try to simply
select OF and OF_IRQ for this then? It's one of those
"warning: (PINCTRL_MSM8X74) selects PINCTRL_MSM which has
unmet direct dependencies (PINCTRL && OF)" that I simply
cannot find my way out of :-/
This uses the new API for tagging GPIO lines as in use by
IRQs. This enforces a few semantic checks on how the underlying
GPIO line is used.
