[PATCH v4 02/39] bnxt: add HWRM init code

[Stephen Hurd <stephen.hurd@broadcom.com>]

From: Ajit Khaparde <ajit.khaparde@broadcom.com>

Start adding support to use the HWRM API.
Hardware Resource Manager or HWRM in short, is a set of API provided
by the firmware running in the ASIC to manage the various resources.

Initial commit just performs necessary HWRM queries for init, then
fails as before.

The used HWRM calls so far:
bnxt_hwrm_func_qcaps:
	Queries device capabilities.

bnxt_hwrm_ver_get:
	Gets the firmware version and interface specifications.
	Returns an error if the firmware on the device is not
	supported by the driver and ensures the response space
	is large enough for the largest possible response.

bnxt_hwrm_queue_qportcfg:
	Required to get the default queue ID.

v4:
Fix few issues highlighted by checkpatch.
