Remove the 32bit DMA restrictions in the emlxs driver
The emlxs driver explicitly restricts DMA memory allocations to 32 bit addresses.
Yet, the driver uses the full high/low address support for physical addresses, it just restricts the allocation to low addresses. I suspect this is a misconception inherited from when Illumos was restricted to <4G PCI addresses.
Along with #12350, I have been running with this restriction removed.
