Subject: misc: hpilo: switch from 'pci_' to 'dma_' API

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

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'ilo_ccb_setup()' GFP_ATOMIC must be used
because a spin_lock is hold in 'ilo_open()' before calling
'ilo_ccb_setup()'
