Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.

This reverts commit 6a9568401cbf8bed89d1f63dae61a07a83a20b50.
Will be replaced with upstreamed solution instead, that just
bumped number of TLBs to 64 in original 34Kf CPU model.

In order to improve performance of qemumips autobuilder
test runs, let's use 34Kf-64tlb cpu type that was introduced
in OE version of qemu. 34Kf-64tlb cpu type is identical to
34Kf but it has 64 TLBs configure vs original 16 TLBs.
The change in number of TLBs in emulated CPU reduces
TLB trash and reduces number of times TLB refill kernel
code runs, and therefore siginificantly improves tests
execution time.
Note 34Kf-64tlb qemu cpu type does not exist in upstream,
so far it is added as patch in OE. See qemu 34Kf-64tlb
cpu addition commit for more details.

Few years ago we switched to using mips32r2 tunings for qemumips however
the default CPU emulation still remained 24Kf which is not optimal for
mips32r2 ISA for qemu [1], therefore switch to recommended 32Kf for CPU
emulation when running qemu in system mode
Boot time to console is ~1s faster with this setting, hopefully this
should speed up qemumips in general

Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that
the value could serve as a default value and could be easily overridden in
configuration files like local.conf.
When using the default value for SERIAL_CONSOLES in qemux86-64,we would have
annoying messages on console complaining about respawning getty on ttyS1.
Although the value is set by purpose, at least we need to provide an easy way
to override it.

qemu can freeze and stop responding if the socket buffer connected to a tcp
serial connection fills up. This happens of course when the reader of
the serial data doesn't actually read it.
This happened in the qemurunner code, because after checking for the
"login:" sentinel, data was never again read from the serial connection.
This patch solves the potential freeze by adding a thread to continuously
read the data from the console and log it. So it also will give a full log
of the console, rather than just up to the login prompt.
To simplify this patch, another serial port was also added to use for the
sole purpose of watching for the sentinel as well as being the interactive
serial port. This will also prevent the possibility of lots of debug
data on the console preventing the sentinel value from being seen due to
interleaved text.

The MIPS emulation for qemumips actually supports
mips32r2:
isa : mips1 mips2 mips32r1 mips32r2
We should probably use that tuning file.
This implicitly changes the default value of DEFAULTTUNE to
mips32r2.

There is currently consideradble confusion over how the tune files operate
and how these interact with the rest of the build system. This update/overhaul
changes things so the tune files are primarily resonsible for setting:
TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that
represents the architecture we're targetting.
TUNE_PKGARCH - The value that represents the tune confuration that this set
of tune parameters results in.
This allows the significant improvement that the core can now always determine
the target architecture value, even when TARGET_ARCH needs to be reset to
something different and likewise, there is one package architecture variable
the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH
and FEED_ARCH variables.

The different kernel recipes encapsulate functionality groups for machines,
therefore it makes sense to have all the QEMU machines using the same kernel
recipe.
Switch the QEMU machines to default to the "linux" recipes for their kernel
and bump the latest recipe from linux-2.6.32 to 2.6.33.
