coreboot: introduce arch_payload_run()
The selfboot() function relied on global variables
within the selfboot.c compilation unit. Now that the
bounce buffer is a part of struct payload use a new
architecture-specific arch_payload_run() function
for jumping to the payload. selfboot() can then be
removed.
