[SCSI] lpfc: hgp/pgp cleanups
From: Christoph Hellwig <hch@lst.de>: - rename PGP/HPH to lpfc_pgp/lpfc_hgp - use __le32 types for the members to start fixing sparse -Wbitwise issues - remove lpfc_sli.MBhostaddr, we can always use the pointer from SLI2_DESC directly Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
