Currently dropbear does not run in background because devtmps and tmpfs
is not enabled by default. Enable devtmps and tmpfs to fix this issue.

The microblaze uses the legacy APIs to dig out a GPIO pin
defined in the root of the device tree to issue a hard
reset of the platform.
Asserting a hard reset should be done using the standard
DT-enabled and fully GPIO descriptor aware driver in
drivers/power/reset/gpio-restart.c using the bindings
from Documentation/devicetree/bindings/power/reset/gpio-restart.txt
To achieve this, first make sure microblaze makes use of
the standard kernel restart path utilizing do_kernel_restart()
from <linux/reboot.h>. Put in some grace time and an
emergency print if the restart does not properly assert.
As this is basic platform functionality we patch the DTS
file and defconfig in one go for a lockstep change.

CONFIG_KEYS_DEBUG_PROC_KEYS is no longer an option as /proc/keys is now
mandatory if the keyrings facility is enabled (it's used by libkeyutils in
userspace).
The defconfig references were removed with:
perl -p -i -e 's/CONFIG_KEYS_DEBUG_PROC_KEYS=y\n//' \
`git grep -l CONFIG_KEYS_DEBUG_PROC_KEYS=y`
and the integrity Kconfig fixed by hand.

The main reason is 0-day testing system which can directly
use these defconfigs for testing.
Enable support for all xilinx drivers which Microblaze
can use and disable dependency on external rootfs.cpio.
There is only one exception which is axi ethernet driver
which still uses NO_IRQ which is not defined for Microblaze.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
