riscv: add trampoline in MBR block to support boot mode 1
...
Add "j pc + 0x0800" at the beginning of the MBR to jump to bootblock.
Tested on hardware:
boot mode 15: works as before
boot mode 1: jump to bootblock works, but bootblock needs to be modified to
move the stack to L2LIM. This will be in a separate commit.
Further changes are needed in the bootblock
