This patch introduces all the structures used by the driver for
communicating with the Hardware. This file is the equivalent of
the bnxt_hsi.h used by bnxt_en driver.
v2: Remove duplicate structure definitions from bnxt_en HSI file and
include bnxt_hsi.h from bnxt_en driver
v3: Remove the checkpatch warnings for coloumns more than 80 characters
