mx5: Optimize lowlevel_init code size
Optimize mx5 lowlevel_init.S code size:
- Compute values at compile time rather than at runtime where possible.
- Assign r4 to hold the zero value rather than setting registers to 0 again and
again.
- Associate a function to setup_pll rather than expanding its large macro code
multiple times.
- Allocate constant values in section only if used.
