riscv: simplify longjmp

The value returned by setjmp must be nonzero. If zero is passed as
parameter it must be replaced by 1.

This patch reduces the code size a bit.

riscv: rename CPU_RISCV_32/64 to match architecture names ARCH_RV32I/64I

RISC-V defines the base integer instruction sets as RV32I and RV64I.
Rename CPU_RISCV_32 and CPU_RISCV_64 to ARCH_RV32I and ARCH_RV64I to
match this convention.

riscv: Add setjmp/longjmp code

To support efi_loader we need to have platform support for setjmp/longjmp.
Add it here.
