[ion/device] Remove ad-hoc compiler optimizations

Browse Source 
Since we hand-specify which regs/regs.h functions shoudl be inlined, we
don't need to depend on specific compiler optimization levels.

# When using the register.h C++ file in production mode, we expect the compiler
# to completely inline all bit manipulations. For some reason, if we build using
# the -Os optimization flag, GCC doesn't inline everything and and ends up
# emitting calls to aeabi_llsl for 64-bits registers. This is very sub-optimal
# so we're enforcing -O3 for this specific file.
