cpukit: RISC-V - make riscv32 code work for riscv64 - v2

  • Use #ifdefs for 32/64 bit code
  • Use unsigned long which is 32-bit on riscv32 and 64-bit on riscv64 (register size)
  • Move the code to a new shared riscv folder to be shared between riscv32 and riscv64
  • Rename RTEMS_CPU extracted from command line to shared riscv target s/riscv*/riscv

Update #3109
  • Property mode set to 100644

[dfe7746e]1dnl canonicalize target cpu
[6c77bba]2dnl NOTE: Most rtems targets do not fullfil autoconf's
3dnl target naming conventions "processor-vendor-os"
4dnl Therefore autoconf's AC_CANONICAL_TARGET will fail for them
5dnl and we have to fix it for rtems ourselves
