Physical refactoring of 82xx adapter register dump utility.

Move register dump routines to new file qlcnic_minidump.c
Existing register dump routines has coding style issues, the code
is moved to the new file without fixing the style issues.

There is a seperate patch to fix the style issues in qlcnic_minidump.c

The above warnings are originating from the macros QLCNIC_RD_DUMP_REG and
QLCNIC_WR_DUMP_REG.
The warnings are fixed and macros are replaced with equivalent functions
in the only file from where it is called.

The following warnings are fixed by making the functions static.

fw to add same. There are checks in driver to ensure send command doesn't fail
before adding mac address in local list.

But instead fix should be:
Add mac address in fw and if it succeeds, add it in driver local list.

Following changes have been added to enable the adapter to work in
NIC partitioning mode where multiple PCI functions of an adapter port can
be configured to work as NIC functions. The first function that is enumerated on
the PCI bus assumes the role of management function which, besides being able
to do all the NIC functionality, can configure other NIC partitions. Other NIC
functions can be configured as privileged or non privileged functions.
Privileged function can not configure other NIC functions but can do all the
NIC functionality including any firmware initialization, chip reset etc. Non
privileged functions can do only basic IO. For chip reset etc, it depends on the
privilege or management function.

1. Added code to determine PCI function number independent of kernel API.
2. Added Driver - FW version 2.0 support.
3. Changed producer and consumer register offset calculation.
4. Added management and privileged operation modes for npar functions. A module
 parameter has been added to control it.
5. Added support for configuring the eswitch in the adapter.
