Philipp Hug 2326a284ac 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
