cfebb5a5c1 risc-v: Move common memory map to its own file from riscv_internal 
Move the linker defined symbols to a separate file, so they can be
accessed without pulling in everything from riscv_internal.h and
whatever it includes (e.g. syscall.h drags in a lot).

b0a71ce3e7 RISC-V: Remove riscv_cpuindex.c from platforms that don't need it

this file from platforms that don't need it.

Also fixes make warning:

c15b6701ce RISC-V: Implement option to run NuttX in supervisor mode (S-mode) 
- Add config "ARCH_USE_S_MODE" which controls whether the kernel
  runs in M-mode or S-mode
- Add more MSTATUS and most of the SSTATUS register definitions
- Add more MIP flags for interrupt delegation
- Add handling of interrupts from S-mode
- Add handling of FPU from S-mode
- Add new context handling functions that are not dependent on the trap
  handlers / ecall

NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
      thus S-mode is not usable as is, yet.
