bae686e127 arch/riscv: force using encoding macro for CSR access
Using CSR name depends on compiler support heavily, but CSR
encoding does not have this problem. It also make it easy to
add new CSR support even if the compiler does not support.

Unify CSR access by using the CSR encoding macro.

ea8682572c build/cmake: add initial KERNEL mode support
Currently only FLAT mode development can enjoy cmake build system. This
patch tries to add initial kernel mode support. It can build NuttX kernel
and libproxies.a, the latter will be further checked though.

This can already help to build an AMP remote node image as it can share
userland apps living in the AMP master node.

Major changes:

- in top folder:
  - CMakeLists.txt    adjust for KERNEL mode, separate from PROTECTED mode.
- in `syscall`:
  - CMakeLists.txt    add mksyscall target for stubs/proxies generation
- in `syscall/stubs`:
  - CMakeLists.txt    use dependency to mksyscall
- in `syscall/proxies`:
  - CMakeLists.txt    use dependency to mksyscall
- in `arch`:
  - CMakeLists.txt    separate KERNEL from PROTECTED mode.
- in `arch/risc-v/src`:
  - CMakeLists.txt    separate from PROTECTED mode, add sub folders.
- in `arch/risc-v/common`:
  - CMakeLists.txt    add sources and sub-folders for KERNEL mode.
- in `arch/risc-v/k230`:
  - CMakeLists.txt    add sources for KERNEL mode.
- in `boards/risc-v/k230/canmv230/src`:
  - CMakeLists.txt    adjust k230 specific scripts for kernel mode.

New additions:

- in `arch/risc-v/src/nuttsbi/`           add CMakeLists.txt
- in `arch/risc-v/src/common/supervisor/` add CMakeLists.txt

c67502d9b4 riscv: Implement page-fault exception and on-demand paging
When an application is being loaded `up_addrenv_create ` calls
`create_region` to create the address environment. Only the first
entry is mapped when the region is created. Virtual memory that is
not mapped will trigger an exception when accessed. Other memory
pages are allocated and mapped on-demand. This enables setting
larger heap and stack for the process without compromising the
overall system memory.

Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.

Resolve:
Move arm64_restorestate() after enter_critical_section() done
