This adds support for GRLIB GPTIMER general purpose timer used in
LEON3/4/5 systems.
One of the GPTIMER subtimers is used to generate periodic interrutps
for announcing ticks. Another subtimer is used as upcounter for the
cycle_get_32() service.

Zephyr SDK version 0.11.3, 0.11.4 and 0.12.0-beta-1 does not have
the required SPARC target support.
Zephyr CI is currently using SDK 0.11.3, which causes the following
build error:
CMake Error at /workdir/zephyr/cmake/compiler/gcc/target.cmake:10
(message):
C compiler /opt/sdk/zephyr-sdk-0.11.3//bin/-gcc not found - Please

This patch adds a workaround such that the SDK target.cmake is picked
up from the directory 0.11 when ARCH=sparc.

SPARC is an open and royalty free processor architecture.
This commit provides SPARC architecture support to Zephyr. It is
compatible with the SPARC V8 specification and the SPARC ABI and is
independent of processor implementation.
Functionality specific to SPRAC processor implementations should
go in soc/sparc. One example is the LEON3 SOC which is part of this
patch set.
The architecture port is fully SPARC ABI compatible, including trap
handlers and interrupt context.
Number of implemented register windows can be configured.
Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic
instructions from SPARC V9. An option has been defined in the
architecture port to forward the corresponding code-generation option
to the compiler.
Stack size related config options have been defined in sparc/Kconfig
to match the SPARC ABI.

This commit eliminates a compilation error by passing int to va_arg
rather than mode_t on SPARC.
Newlib sys/_types.h defines mode_t for SPARC as:
typedef unsigned short __mode_t;
GCC 10.2.0 gave the following error message and suggested solution:
mqueue.c: In function 'mq_open':
mqueue.c:61:21: error: 'mode_t' {aka 'short unsigned int'} is promoted
to 'int' when passed through '...' [-Werror]
61 | mode = va_arg(va, mode_t);
| ^
mqueue.c:61:21: note: (so you should pass 'int' not 'mode_t' {aka 'short
unsigned int'} to 'va_arg')

Neither i2c_transfer in i2c.h nor i2c_mcux_transfer in i2c_mcux.c
have any sort of locking. If e.g. an i2c eprom is updated using a
shell and simultaneously another thread access a lm75 then one
of the two transfers will fail or produce a random result.
This changes addresses this issue by that all i2c_msgs of one
i2c_transfer are completed before allowing a subsequent transfer
to start.
The code has been validated on a FRDM_K64F.

This commit adds a C99 stdio value formatter capability where
generated text is emitted through a callback. This allows generation
of arbitrarily long output without a buffer, functionality that is
core to printk, logging, and other system and application needs.
The formatter supports most C99 specifications, excluding:
* %Lf long double conversion
* wide character output
Kconfig options allow disabling features like floating-point
conversion if they are not necessary. By default most conversions are
enabled.
The original z_vprintk() implementation is adapted to meet the
interface requirements of cbvprintf, and made available as an opt-in
feature for space-constrained applications that do not need full
formatting support.
