Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.

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.

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

The image must be placed into:
boards/risc-v/mpfs/icicle/include/boot_romfsimg.h
The image is mounted by mpfs_bringup, which is run by the application
itself, or by board_late_initialize() in the case when
CONFIG_BOARD_LATE_INITIALIZE is defined, e.g. with CONFIG_BUILD_KERNEL
- Add test for mode support, which is architecture dependent
- Add tests for address alignment and region size
- Add option to query for access rights
- The function goes through every PMP entry and tests if an address
range from [base, base+size] has been configured for desired
access rights.
- If several PMP entries match the range and access rights, the
information is combined
- End result is either no access, a partial match was found, or a full
match was found. Details about the partial match are not provided.
The intent for testing access rights and not just blindly applying them
is a case where they are already set in e.g. a bootloader. In this
case, nothing should be done, unless the configuration does not match,
in which case the software must not continue further.
NOTE: THIS ONLY WORKS WHEN KERNEL RUNS IN M-MODE FOR NOW
This frees the PMP for other use, e.g. HART memory separation.
The page tables are statically allocated, 1 per level.
This feature is now behind CONFIG_MPFS_USE_MMU_AS_MPU, because
only the MPFS target supports this (others are not tested).
If the MMU is used for memory separation within a HART, the PMP must
still be configured to allow user access to the memory mapped for the
HART, because PMP *rekoves* access by default. At this point all of
the user memory as well as the kernel RAM are opened.
A more flexible solution for PMP configuration will follow.
The old implementation used the default ld.script for the kernel side
which did not obey the memory.ld limits whatsoever.
Also, provide the user space addresses from the linker script to get rid
of the pre-processor macros that define (incorrect) default values for
the user space composition.

- select whether the hart boots via opensbi or not.
CONFIG_MPFS_HARTx_ENTRYPOINT :

from SBI if CONFIG_MPFS_HARTx_SBI is set
