This patch changes variable name 'fn' to 'pf' of structure adapter.
A 'fn' usually stands for PCI function which could be a PF or a VF.
However, the use of this particular variable is explicitly limited to PF
only. So, be specific about it in the variable name.

Also corrects arguments passed for fn t4_ofld_eq_free, t4_ctrl_eq_free,
t4_eth_eq_free, t4_iq_free, t4_alloc_vi, t4_fw_hello, t4_wr_mbox and
t4_cfg_pfvf function.

Also renames cxgb4_t4_bar2_sge_qregs to t4_bar2_sge_qregs and renames
the latter function name in cxgb4vf driver to t4vf_bar2_sge_qregs to
avoid conflicts. Also fixes alignment for these function.

Fix up some ->d_inode accesses in the chelsio driver.

 (1) FILE_DATA() should just be replaced with file_inode().

 (2) set_debugfs_file_size() should be removed and debugfs_create_file_size()
     should be used to create the file.

To allow for better scalability on systems with large core counts, we
will try and allocate enough RDMA Concentrator IQs and MSI/X vectors as
we have cores. If we cannot get enough MSI/X vectors, fall back to the
minimum required: 1 per adapter rx channel.

Also clean up cxgb_enable_msix() to make it readable and correct a bug
where the vectors are not correctly assigned if the driver doesn't get
the full amount requested.

Various patches have ended up changing the style of the symbolic macros/register
to different style.

As a result, the current kernel.org files are a mix of different macro styles.
Since this macro/register defines is used by different drivers a
few patch series have ended up adding duplicate macro/register define entries
with different styles. This makes these register define/macro files a complete
mess and we want to make them clean and consistent. This patch cleans up a part
of it.
