Display text strings on parallel interfacing HD44780 based
generic LCD controller using GPIO pins to interface with
Arduino Due(SAM3). HD44780 is a popular controller and an
example can help using gpio pins in parallel with it. I
have tested it on JHD20x4 LCD panel for 4Bits & 8Bits
configuration. The code has been made generic so that user
can modify quite a few options.

Since firq utilizes a 2nd register bank, and since all of those
many GPRs can be used, the strategy here is to save extra registers,
such as lp_count, lp_start, lp_end into callee saved registers.
These registers are safe to use because the C-ABI followed by the
compiler will cause these to be spilled to the stack if a C function
wants to use them. By selecting upper GPRs, r23-r25, it is very unlikely
the compiler will spill them. This improvement, therefore, can avoid a
d-cache miss since we are avoding memory altogether when saving these.
The struct firq_regs is no longer needed.

It was found that the test latency_measure, when compiled
for microkernel, would fail on the ARC. This because the
trap handler, used by irq_offload, wasn't supporting thread switching.
This submission adds the code to do that, and the code size is
bigger only when CONFIG_MICROKERNEL is defined.
To keep code a bit smaller, there is a trick exploited here where
the AE bit is cleared in the STATUS32 register and in AUX_IRQ_ACT,
bit 1 is set, to make it appear as if the machine has interrupted
at priority 1 level. It then can jump into some common interrupt
exit code for regular interrupts and perform an RTIE instruction
to switch into the new thread.
test/latency_measure/microkernel now passes.

Moved setting of specific Cortex-M compiler flags in each SoC directory
unify setting them in the arch/arm/soc Makefile.
Add flags for Cortex M0, M0+, M1, M3, M4, and M7. However only
CONFIG_CPU_CORTEX_M3 and CONFIG_CPU_CORTEX_M4 are supported at this time
As part of this change converted Kbuild files for some SoCs into
Makefiles as the Makefiles would be empty otherwise.

so the multicast would fail always anyway and the program
