Subject: [PATCH] UPSTREAM: arch/riscv: Move _start to the beginning of the
 bootblock

The different entry points (0x100, 0x140, ...), which were defined in
the RISC-V Privileged Specification 1.7, aren't used anymore. Instead
the Spike bootrom jumps at the start of our image, and traps are handled
through mtvec.
