ENGR00286273-2 misc: sram: Set default alignment to 4Kbytes

As Kernel 3.0.35 does, we set the default iram alignment to 4Kbytes,
although it would waste few memory space.

We here try to do this as an expediency because currently we couldn't
find a perfect solution for 4Kbytes alignment requirement from SDMA.
