For up_irq_disable, use XCHAL_EXCM_LEVEL
For up_irq_save, use XCHAL_IRQ_LEVEL.
Then we can use svcall in enter_crritical_section.

arch/arm/src/efm32/efm32_start.c:
/* For the case of the separate user-/kernel-space build, perform whatever
* platform specific initialization of the user memory is required.
* Normally this just means initializing the user space .data and .bss
* segments.
*/
#ifdef CONFIG_NUTTX_KERNEL
efm32_userspace();
showprogress('E');
#endif
But there is no CONFIG_NUTTX_KERNEL configuration setting. Comparing this to other architectures it is clear this should be
#ifdef CONFIG_BUILD_PROTECTED
here is the reason:
1.clock_systime_timespec(core function) always exist regardless the setting
2.CLOCK_MONOTONIC is a foundamental clock type required by many places

Reason: xtensa svcall only have level-1 interrupt level.
Sush do not generate interrupt when up_irq_save.
Software int can generate interrupt when up_irq_save.

This commit fixes at least two issues.
* Fix a build with clang on linux
```
/usr/bin/ld: cannot open linker script file nuttx.ld: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
* Restore symbol renaming for clang on linux
I guess it actually depends on the linker.
For now, use CONFIG_HOST_MACOS.
This fixed the following crash seen with sim/linux built with clang.

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build

State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

Fix the CPU1 idle tasks stack corruption since the cpux's idle stack
is loaded from g_cpu_basestack (data section) before, but on this time
it maybe not ready since it is initialized by CPU0, and the value
from g_cpu_basestack is random.

commit 328374f4658d11655f268f968f4c6c7a3942f320
changed the wait to use usleep. This killed the
write performace from the published values in the
datasheet of ~100 us to 2 mS per 256 bits. On
a 1000 per tick config. It can be 10 X worse
on the default 100 per tick config.
This changes uses up_udelay.
Architecture support for STMicroelectronics STMU585xx MCUs. This is
based on corresponding code for STM32L5, but has been considerably
adjusted. Tested with a B-U585I-IOT02A board and a simple NSH
configuration, but only running NuttX in the non-secure world with
TrustedFirmware-M.

This commit adds initial support for PWM driver to SAM MCU series.
Only general PWM on PWMH output is currently supported, complementary
output on PWML is not allowed. The current state of the driver also does
not support external triggering of other perihperals.
Multichannel option is supported. The functionality of the driver was
tested on an example pwm application and with a real time control system.
