aha1532: remove ISA_DMA_THRESHOLD usage
We can safely remove ISA_DMA_THRESHOLD usage in aha1542. aha1542 uses
ISA_DMA_THRESHOLD to see if:
- the buffers in scatter/list are below 16MB.
- scsi_host is below 16MB.
Both checkings were added in the ancient times but aren't necessary
nowadays since we properly bounce the buffers and allocate scsi_host
below 16MB with non-zero unchecked_isa_dma.
