Disable zone DMA32 for shiba and husky

Browse source 
Same as P22, P23 do not have 32-bit address limitation in hardware, so
we would like to empty zone DMA32 for better performance and simplify
memory management.

Bug: 263239622
Test: b/270096808, b/270097444. Pass reboot test and run sst for 100+
hours without obvious issues.
