The wrappers in include/linux/pci-dma-compat.h should go away.

'mpt_alloc_fw_memory()' should still use GFP_ATOMIC, because it can be
called from 'mpt_do_upload()' which might sleep.

Instead of using GFP_ATOMIC, we could pass the 'sleepFlag' from
'mpt_do_upload()' and check all other callers to pass the expected flag.
