* implement DIRECT IRQ support both for normal irq and fast irq.
* add separate interrupt stack for fast irq and use CONFIG_ARC_
_FIRQ_STACK to control it. This will bring shortest interrupt
latency for fast irq.
* note that scheduing in DIRECT IRQ is not supported.

This commit introduces the cmake extension zephyr_library_amend.
This function allows for adding files in an out-of-tree Zephyr module
to a zephyr library created in zephyr repo CMake files.
As example:
drivers/entropy/CMakeLists.txt creates an zephyr library as:
zephyr_library()
only available to zephyr itself.
The amend function allows to amend to such a lib, by creating a
CMakeLists.txt file following identical folder structure in a Zephyr
Module:
<zephyr_module_oot>/drivers/entropy/CMakeLists.txt
zephyr_library_amend()
zephyr_library_sources() # Sources are amended to the original library

Depending on LiteX configuration, CSRs
(control&status registers) might be split
into several consecutive registers.
This introduces common helper functions
for all LiteX drivers providing access
to CSRs for a default LiteX configuration
(data_width = 8bit, bus_width = 32bit).

The intel64 switch implementation doesn't actually use a switch handle
per se, just the raw thread struct pointers which get stored into the
handle field. This works fine for normally initialized threads, but
when switching out of a dummy thread at initialization, nothing has
initialized that field and the code was dumping registers into the
bottom of memory through the resulting NULL pointer.
Fix this by skipping the load of the field value and just using an
offset instead to get the struct address, which is actually slightly
faster anyway (a SUB immediate instruction vs. the load).
Actually for extra credit we could even move the switch_handle field
to the top of the thread struct and eliminate the instruction
entirely, though if we did that it's probably worth adding some
conditional code to make the switch_handle field disappear entirely.

We should be adding a compiler barrier for IP and SP
registers when we are doing syscall generation on
ARMv6-M architecture. The syscall generation itself
only does an SVC trigger; the execution returns to
thread mode and ARM does not guarantee that IP
register is preserved, when we finally get back to
the point where the syscall was invoked. The SP
also needs to be preserved for syscalls returning
64-bit results. In that case the r0 may hold a
pointer to the stack where the 64-bit result was
pushed, That is, the stack pointer may have been
changed due to the syscall, and C code needs to
know that.

The existing implementation used HAS_CMSIS configuration to specify
that CMSIS-Core(M) is used; when, in fact, there are other CMSIS
variants available such as CMSIS-Core(A) and CMSIS-DSP available.
This commit replaces the existing HAS_CMSIS configuration with
HAS_CMSIS_CORE to clarify that CMSIS-Core is used. It also introduces
the CMSIS-Core variant configuration, HAS_CMSIS_CORE_M, that is
automatically selected when HAS_CMSIS_CORE is enabled.
