arm: Move exception_init() close to console_init()

This patch adds stub implementations of exception_init() to all archs
so that it can be called from src/lib/hardwaremain.c. It also moves/adds
all other invocations of exception_init() (which needs to be rerun in
every stage) close to console_init(), in the hopes that it will be less
likely overlooked when creating future boards. Also added (an
ineffective) one to the armv4 bootblock implementations for consistency
and in case we want to implement it later.
