FS#10114 - Sansa AMS : use IRAM for codecs on >2MB targets Rafaël Carré

Browse source 
Activates IRAM for AMS Sansas to be used by codecs and core. Fixes Reboot-on-mp3 and gives speed up on codecs using IRAM in general.
I've made a change: the core/codec ratio is 0x20000/0x30000 instead of 0x10000/0x40000, 0x30000 is way more than codecs currently use (0x14000 at max) and the core might need more than 0x10000.
