[Marvell-armhf] Fix SDK DMA allocation failure (sonic-net#20165)

Why I did it
Fix DMA memory allocation failure seen when SDK drivers where failed to find size aligned memory.
pci 0000:01:00.0: dma_alloc_coherent failed to allocate aligned size of 0x200000 for phys0xbf300000

How I did it
Fix DMA driver alloc failure by adding more retries and moving the free for unaligned allocation to the end of allocation logic.
Increase CMA memory to 32MB to allow for more retries.

How to verify it
Run SONIC PTF with fixes for armhf-nokia_ixs7215_52x-r0 platform.
