gpio: rcar: Add Runtime PM handling for interrupts
The R-Car GPIO driver handles Runtime PM for requested GPIOs only.
When using a GPIO purely as an interrupt source, no Runtime PM handling
is done, and the GPIO module's clock may not be enabled.
To fix this:
- Add .irq_request_resources() and .irq_release_resources() callbacks
to handle Runtime PM when an interrupt is requested,
- Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM
when e.g. disabling/enabling an interrupt, or configuring the
interrupt type.

gpio: Propagate all errors in devm_get_gpiod_from_child()
devm_get_gpiod_from_child() tries several property suffixes to find a
GPIO descriptor. If all suffixes fail and no probe deferral has been
detected, it returns the error of the last try.
However, if any but the last try fails with a real error (e.g. -EBUSY),
this error is not propagated, and -ENOENT will be returned.
This confuses drivers that e.g. want to detect if a GPIO is already in
use.
To fix this, change the loop logic to continue on -ENOENT, which
indicates the property was not found and the next suffix should be
tried, and propagate all other detected errors.

gpio: add userspace ABI for GPIO line information
This adds a GPIO line ABI for getting name, label and a few select
flags from the kernel.
This hides the kernel internals and only tells userspace what it
may need to know: the different in-kernel consumers are masked
behind the flag "kernel" and that is all userspace needs to know.
However electric characteristics like active low, open drain etc
are reflected to userspace, as this is important information.
We provide information on all lines on all chips, later on we will
likely add a flag for the chardev consumer so we can filter and
display only the lines userspace actually uses in e.g. lsgpio,
but then we first need an ABI for userspace to grab and use
(get/set/select direction) a GPIO line.
Sample output from "lsgpio" on ux500:
GPIO chip: gpiochip7, "
8011e000 .gpio", 32 GPIO lines
line 0: unnamed unlabeled
line 1: unnamed unlabeled
(...)
