commonlib/fsp_relocate: add PE32 section support
Recently published Intel CedarIslandFSP binary contains PE images in
FSP-M and FSP-S. This causes coreboot boot hang on DeltaLake servers.
PI spec PI_Spec_1_7_final_Jan_2019 on uefi.org talks about FV files
requiring to support SECTION_PE32 sections and FSP specification
states that FSP images are created in alignment with PI specification.
FSP images are relocated at build time and run time using the func
fsp_component_relocate. That code only supported TE image relocation
so far.
The change required to add support for pe_relocate in fsp-relocate.c
I had to move a few functions to top of file as they need to be used
by pe_relocate but were placed below the te_relocate function. I chose
to place pe_relocate function next to te_relocate.
The code supports PE32 format, not PE32+, at this time.
Links for PE and FSP specs are provided below for reference.

TESTED=
This code is tested with FSP version 33A for DeltaLake boot which has
FSP-M and FSP-S as PE32 sections. This FSP version does not boot on
DeltaLake without this change.
