9cd73bf859 openrisc: fix relocation code
The relocation code can now relocate from anywhere to
the RAM.

The old code assumed that the binary was copied to the RAM
by some PBL and then it just relocated the .text section
from the loaded address to the linked address.

Now, it first checks if vectors are somewhere else than the
linked address. If yes, there are copied to address 0 (or
to the exception vector base address if register EVBAR is
present).

Then, the .text section is relocated from its current location
to the RAM.

3874a37745 openrisc: Work around potential relocation issues
When reset code is in flash, the jump instructions emitted by the
compiler are relative instead of absolute jumps.

A fix to the reset code to make correct jumps to the beginning of
code relocated to RAM have also been added.
