Move __bid128 functions off QSPI

Apparently, executing code from QSPI on battery power is
not reliable on the DM42. The machine essentially hangs,
and resumes execution when you plug the USB.

This will seriously limit how much extra legroom we have
for code on DB48X. This might make it more urgent than anticipated
to re-code the floating point stuff more efficiently.

Fixes #12
