FS#10495 - More stable MP3 playing for Sansa Clip v1

This patch reserves the full IRAM for the Codec.
Playing 196kbit/s VBS MP3s is more stable with this patch.
I do not know the reason for this. Either there is interference between CODEC and other loaded memory segments in IRAM or the Codec just needs more space.
Influence on plugins and Fuze is not tested.

a better fix is in fs#10605

Moving around things in memory does seem to make playback better or worse on the clip, presumably because some area of memory is overwritten and shuffling like this increases the odds that nothing important is corrupted. However I do not think this is an actual fix.

Regarding memory, MP3 needs about 110KB of RAM:

Since MP3 does not use malloc, lack of memory will cause a compiler error, but cannot cause runtime problems.
