Board-shooter & board-shooter_u: use MEMTYPE_EBI1 for ADSP

*The size of ADSP has been reduced to 0x1300000 as 720P video capture only requires 0x950000
*ADSP now uses MEMTYPE_EBI1 (should fix the random reboots once and for all)
*Added a 1MB gap between the ADSP and SMI allocations (you can never be too safe)
*Moved ADSP to what was previously the bottom of the SMI allocation
