arcv2: Set IOC aperture so it covers available DDR
We used to use the same memory layout and size for a couple of
boards and thus we just hardcoding IOC aperture start and size.
Now when we're getting more boards with more memory on board we
need to have an ability to set IOC so it matches real DDR layout
and size.
Even though it is not really a must but for simplicity we assume
IOC covers all the DDR we have, that gives us a chance to not
bother where DMA buffers are allocated - any part of DDR is OK.

arc: use timer driver for ARC boards
This commit replaces legacy timer code with usage of arc timer
driver.
It removes arch/arc/lib/time.c file and selects CONFIG_CLK,
CONFIG_TIMER and CONFIG_ARC_TIMER options for all ARC boards by default.
Therefore we remove CONFIG_CLK option from less common axs101 and
axs103 defconfigs.
Also it removes legacy CONFIG_SYS_TIMER_RATE config symbol from
axs10x.h, tb100.h and nsim.h configs files as it is no longer required.

arc: dts: separate single axs10x.dts file
We want to use the same device tree blobs in both Linux and U-Boot for
ARC boards.
Earlier device tree sources in U-Boot were very simplified and hadn't been
updated for quite a long period of time.
So this commit is the first step on the road to unified device tree blobs.
First of all we re-organize device tree sources for AXS10X boards.
As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and
AXC003 cpu tiles respectively we add corresponding device tree source
files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for
cpu tiles and axs101.dts and axs103.dts to represent actual boards.
Also we delete axs10x.dts as it is no longer used.
One more important change - we add timer device to ARC skeleton device
tree sources as both ARC700 and ARCHS cores contain such timer.
We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree
sources as it is referenced via phandle from timer node in common
skeleton.dtsi file.

arc: Update exception & interrupt handling for ARCv2
Initially IVT for ARCv2 was simply copypasted from ARCompact
with some selected fixes so basic stuff works.
Now we update it with more ARCv2 specific vectors like
* Software Interrupt
* Division by zero
* Data cache consistency error
* Misaligned access
Also normal interrupts are now implemented properly and extened to
all possible 240 items.

arc: make global_data.h usable in assembly files

./arch/arc/include/asm/global_data.h: Assembler messages:
./arch/arc/include/asm/global_data.h:11: Error: bad instruction 'struct arch_global_data{'

scripts/Makefile.build:316: recipe for target 'arch/arc/lib/start.o' failed
-------------------->8-----------------
In this change we disable struct arch_global_data in ASM which fixes
the issue above.
