rbcodec dsp: Remove INIT_ATTR from the DSP library

All of these are technically unsafe cross-section references but
most aren't reported by the linker, probably due to inlining. In
practice there was no problem because the affected code was only
run at init time anyway.

For now, remove INIT_ATTR until the init code can be refactored
to avoid the problematic references. This should also save code
size by moving more code to the init section.

dsp_init() gets to keep its attribute because it's already OK.
