By just moving the atmel_gpio_to_irq() and calling the internal
function we can get rid of the driver calling back out into the
deprecated external consumer API.

Sharing the same irqchip with multiple gpiochips is not a good
practice. For instance, when installing hooks, we change the state
of the irqchip. The initial state of the irqchip for the second
gpiochip to register is then disrupted.

Smatch complains about this condition:
if (has_config && num_pins >= 1)
The "has_config" variable is either uninitialized or true. The
"num_pins" variable is unsigned and we verified that it is non-zero on
the lines before so we know "num_pines >= 1" is true. Really, we could
just check "num_configs" directly and remove the "has_config" variable.

It looks like we parse the drive strength setting here, but never
actually write it into the hardware to update it. Parse the setting and
then write it at the end of the pinconf setting function so that it
actually sticks in the hardware.

If you look at "pinconf-groups" in debugfs for ssbi-mpp you'll notice
it looks like nonsense.
The problem is fairly well described in commit 1cf86bc21257 ("pinctrl:
qcom: spmi-gpio: Fix pmic_gpio_config_get() to be compliant") and
commit 05e0c828955c ("pinctrl: msm: Fix msm_config_group_get() to be
compliant"), but it was pointed out that ssbi-mpp has the same
problem. Let's fix it there too.
NOTE: in case it's helpful to someone reading this, the way to tell
whether to do the -EINVAL or not is to look at the PCONFDUMP for a
given attribute. If the last element (has_arg) is false then you need
to do the -EINVAL trick.
ALSO NOTE: it seems unlikely that the values returned when we try to
get PIN_CONFIG_BIAS_PULL_UP will actually be printed since "has_arg"
is false for that one, but I guess it's still fine to return different
values so I kept doing that. It seems like another driver (ssbi-gpio)
uses a custom attribute (PM8XXX_QCOM_PULL_UP_STRENGTH) for something
similar so maybe a future change should do that here too.

Merge the code of the gpio-ingenic driver into the pinctrl-ingenic

The reason behind this, is that the same hardware block handles both pin
config / muxing and GPIO.

the code is the exact same as what it was in the gpio-ingenic driver.

The pin 327 was supposed to be used as a voltage control line for the
SD card regulator, but the SD card port1 does not support UHS-I. It
only supports 3.3V signaling, hence this pin is pointless.
Just a note about the background. At first, hardware engineers tried
to implement the UHS for this port. Then, they needed to shrink the
silicon die size, and gave up the UHS, but forgot to remove the pin
assignment.

we can set is_generic.
