Remove bounded-pointers relics from am33 code


This patch removes uses of bp-sym.h and BP_SYM from the am33 port.  Given 
the generally bitrotten state of that port I've just committed this patch 
as part of the bounded-pointers removal; it's not possible to test am33 
changes in the present state of the port.
