Rasesh Mody a50d7cbbda net/qede: support registers dump 
Add support for .get_reg eth_dev ops which will be used to collect the
firmware debug data.

PMD on detecting on some HW errors will collect the FW/HW Dump to a
buffer and then it will save it to a file implemented in
qede_save_fw_dump().

Dump file location and name:
Location: <RTE_SDK> or DPDK root
Name: qede_pmd_dump_mm-dd-yy_hh-mm-ss.bin

DPDK applications can initiate a debug data collection by invoking DPDK
library’s rte_eth_dev_get_reg_info() API. This API invokes .get_reg()
interface in the PMD.

PMD implementation of .get_reg() collects the FW/HW Dump, saves it to
data field of rte_dev_reg_info and passes it to the application. It’s
the responsibility of the application to save the FW/HW Dump to a file.
We recommendation using the file name format used by qede_save_fw_dump().
