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

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