struct dfhv0 and dfhv1 sturct used by other function in xfpga , so define dfhv0 and dfhv1 in types_int.h

fpga_guid is compatible with libuuid's uuid_t, so users can use libuuid
fpga_guid is defined in /include/opae/types.h
use fpga_guid varabile

check file_path is null or not
change char* file_path to const har* file_path

define enum_fpga_feature() or find_fpga_feature() new function in common.c file, it enums fpga features and returns dfl_dev.x

Description
Added GUID support (generated using guid generation tool) as per DFHV1 spec.
Made sure update is backwards compatible and usrclk utility can be used with DFHV0 as well as DFHV1 FIM.
Reference Document - https://docs.kernel.org/fpga/dfl.html
Collateral (docs, reports, design examples, case IDs): https://hsdes.intel.com/appstore/article/#/14019248776 (DFHv1 Key IP Driver Support)
Tests run:
usrclk utility on DFHV0 FIM and usrclk utility on DFHV1 FIM.
DFHV1 FIM is special test FIM created by OFS hardware team ,with RAM where we can poke DFHV1 headers.
