This reverts commit 72a95859728a7866522e6633818bebc1c2519b17.
It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances,
which use the syscon driver. Little-endian is not effected, which means
likely it's important to handle regmap_get_val_endian() in this function
after all.

This patch switches the driver away from legacy gpio/of_gpio API to
gpiod API, and removes use of of_get_named_gpio_flags() which I want to
make private to gpiolib.
We also need to patch relevant DTS files, as the original code relied on
the fact that of_get_named_gpio_flags() would fetch any data encoded in
GPIO flags, even if it does not reflect valid flags for a GPIO.

When we consider MFD which implements hotplug (e.g. USB hotplug
driver based on product and vendor IDs) functionality it turns out
that its sub-devices are correctly matched with corresponding device
tree nodes only at the first time. When physical device reboots
or is replugged (and MFD driver is disconnected and probed back
again) all sub-devices fails in mfd_add_device() with error
'Failed to locate of_node'.
The reason of that behavior is that when any MFD sub-device is
created for the first time (and matched with device tree node) it
is added to the mfd_of_node_list. It looks like this list is never
cleaned even if devices added there are intentionally removed from
the system. So when MFD device is replugged and all sub-devices
are matched with their device tree nodes again they fail as matched
nodes already exist in mfd_of_node_list. In other words current
implementation does not support MFD with hotplug feature.
This commit extends MFD core for hotplugging support by removing
appropriate OF node entry from mfd_of_node_list when corresponding
device is removed from the system. Thanks to that when device is
added once again it can be matched with its device tree node
successfully.
