Commit Message

Cross compiling DPDK for BE mode on ARM results into errors
"PMDINFO portal/dpaa2_hw_dpio.o.pmd.c No drivers registered"

The original code assumes the sh_size to be 32 bit, while it can
be Elf32_Word or Elf64_Xword based on 32bit or 64 bit systems.

This patches replaces the sh_size conversion routines to use ADDR_SIZE
