gpio: arizona: Correct handling for reading input GPIOs
The GPIO register is cached since all the configuration resides within
it, however, this means for input GPIOs the driver will not return the
actual state but the last value written to the register cache.
To correct this in the case of reading an input GPIO resume the CODEC
and drop the cache for the input register to ensure an actual hardware
read takes place.

Add a simple, generic, single register fixed-direction GPIO driver.

* gpio-mmio doesn't allow a fixed direction, it assumes there is always
a direction register.
* gpio-74xx-mmio only supports all-in or all-out setups
* gpio-74xx-mmio is DT only, this needs to support legacy too
* they don't double-read when getting the GPIO value, as required by
some implementations that this driver supports
* we need to always do 32-bit reads, which bgpio doesn't guarantee

gpio: return NULL from gpiod_get_optional when GPIOLIB is disabled
Given the intent behind gpiod_get_optional() and friends it does not make
sense to return -ENOSYS when GPIOLIB is disabled: the driver is expected to
work just fine without gpio so let's behave as if gpio was not found.
Otherwise we have to special-case -ENOSYS in drivers.
Note that there was objection that someone might forget to enable GPIOLIB
when dealing with a platform that has device that actually specifies
optional gpio and we'll break it. I find this unconvincing as that would
have to be the *only GPIO* in the system, which is extremely unlikely.

Pull vfs 'statx()' update from Al Viro.
This adds the new extended stat() interface that internally subsumes our
previous stat interfaces, and allows user mode to specify in more detail
what kind of information it wants.
It also allows for some explicit synchronization information to be
passed to the filesystem, which can be relevant for network filesystems:
is the cached value ok, or do you need open/close consistency, or what?
From David Howells.

eliminated quirks, backmerged fixes plus I rebased it to an upstream
SHA1 from yesterday that includes most changes queued up in -next plus
all sched.h changes that were pending from Andrew.

FW should only be told about the buffer space it can DMA to, that

applications should validate the buffers against both MTU and
