Add PIE support for AARCH32
Only BL32 (SP_min) is supported at the moment, BL1 and BL2_AT_EL3 are just
stubbed with _pie_fixup_size=0.
The changes are an adaptation for AARCH32 on what has been done for
PIE support on AARCH64.
The RELA_SECTION is redefined for AARCH32, as the created section is
.rel.dyn and the symbols are .rel*.
