For testing secure->non-secure thread swapping.
This also tests that the FP context is correctly preserved
when calling a secure function.

When ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS is enabled, if FPU is
being used (CONTROL.FPCA == 1), store all FP registers before
entering the secure function, and restore them afterwards.
This is needed if any NS thread or ISR that interrupts the secure
function uses FP registers. If they do, a secure UsageFault occurs
unless this change is applied.
This allows k_sched_lock() and k_sched_unlock() to be dropped when
ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS is enabled.
Enable ARM_NONSECURE_PREEMPTIBLE_SECURE_CALLS by default when
building TF-M.

This adds code to swap_helper.S which does special handling of LR when
the interrupt came from secure. The LR value is stored to memory, and
put back into LR when swapping back to the relevant thread.
Also, add special handling of FP state when switching from secure to
non-secure, since we don't know whether the original non-secure thread
(which called a secure service) was using FP registers, so we always
store them, just in case.

Since Pygments 2.7.0 devicetree syntax is supported, so there is no need
to use a custom lexer. Version 2.9.0 introduces a fix that is required
for some devicetree snippets.

This commit aligns iis2dlpc sensor driver to latest multi
instance sensor driver model.
In particular:
1. make use of some few DT helpers:
- get bus devices with DEVICE_DT_GET
- get SPI information with SPI_CONFIG_DT_INST
- get drdy gpios with GPIO_DT_SPEC_GET
2. make use of the stmemsc common routines and move ctx
handler inside struct config, so that the bus_init
routines can be totally avoided.

We can use build-time offsets from a struct k_thread pointer directly
to struct _callee_saved members. No need to compute that at run time.

SMP support on cAVS is implemented by using uncached addresses
for all writable data sections except for stack, i.e. for .data,
.bss and some other specialised ones. So far that has been
implemented for cAVS 1.5. This patch does the same for cAVS 1.8.

When multithreading is off, kernel source files like sem.c (samphore
implementation) are not present in the build. Some platforms by default
fetch modules or drivers that are using multithreading primitives and
because of that fails to compile when multithreading is off.
Limit the test to only qemu platforms since test is arch specific.
