The patch fixes the compile issue with clang on ARM64, as well as
clang + X86 builing hosts.
Newly introduced #pragma pack(1) in the header file caused comipiling
issues for the files who included it.

~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_hw.h:8:10: error:
the current #pragma
pack alignment value is modified in the included file [-Werror,
-Wpragma-pack]
~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_defines.h:100:9: note:
previous '#pragma pack' directive that modifies alignment is here.
The fix is to change the #pragma pack alignment locally and not have
effect on other files who included this header file.
