qualcommax: disable swiotlb for 64mb in saving.

Browse Source 
Disable software input output translation lookaside buffer (swiotlb) as
it wastes memory on low memory platforms (512m or less)

qualcommax: only disable swiotlb for platforms <= 512M

Disabling swiotlb is only required for platforms with 512M or less to save
64mb.
