These versions of the MicroBlaze CPU are now considerably outdated and
were obsoleted in 2012. Additionally they were only available with the
big endian configuration. Remove the v7.30 tune feature.
The s3adsp1800-qemu-microblazeeb machine emulates a v7.10.d cpu version,
however QEMU does not limit the CPU being emulated and provides all CPU
instructions and features that are available, so build targeting v8.00
instead.
Also fix up the version formatting generated by
microblaze_current_version.

The endianess of a specific architecture could be either big or little,
there is not a third value, so let it default to be little endian, and
get rid of the tune feature 'little-endian' which is redundant to be
there, also change tune feature 'big-endian' to 'bigendian'.
With these changes, it will behave same with all other architectures in
openembedded-core layer.

This change reworks how the meta-xilinx layer enables and provides the
custom version of QEMU based on Xilinx's fork of QEMU. The existing
implementation relied on the single sysroot which was changed in oe-core
such that now recipes have their own sysroots (RSS support).
Additionally oe-core now provides the QEMU binaries to the runqemu
script via the 'qemu-helper-native' recipes sysroot as opposed to the
image sysroot.
These rework changes allow for a single machine to select the targeted
QEMU version as well as to provide the qemuboot config specific to the
targeted QEMU version. The selection of QEMU version is now handled by
PREFERRED_PROVIDER mechanics with the meta-xilinx layer providing an
additional recipe that is equivalent to qemu-helper-native and which
also provides said target allowing for the machine to select via the use
of PREFERRED_PROVIDER_qemu-helper-native. This recipe
(qemu-xilinx-helper-native) however instead provides the sysroot
populated with qemu-xilinx instead of qemu.
Additionally the XILINX_QEMUBOOT variable is replaced with the
qemuboot-xilinx.bbclass, this provides the overrides for setting up
qemu-xilinx specific QB_* args. Additionally this bbclass points runqemu
at the qemu-xilinx-helper-native sysroot for QEMU binaries.
These changes also work towards making the meta-xilinx layer better
handle multiple qemuboot.conf variants as well as handling different
QEMU versions.
This change also removes the 'qemu-system-xilinx' MACHINE_FEATURES, this
is due to MACHINE_FEATURES no longer being available for native recipes.
Additionally there is no longer any logic that needs to know this any
way.

Move the setup of network devices to the new QB_NETWORK_DEVICE variable,
this avoids the need to configure slirp or tap options from the machine
configuration.
Additionally this provides the benefit of letting runqemu handle the
setup of tap and slirp arguments, allowing for it to provide features
such as host-guest port forwarding for slirp.

Rename the QEMU machines to match the <board>-<design>-<arch>
convention. QEMU only machines no longer need to be named qemu*.
Note for qemuzynq it is special in that it does not model a board, as
such it has no board in the name being just 'qemu-zynq7'.
This updates the README.md to match the new machine names.
Additional update all occurrences of the qemu* machines
