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.
