From: Franck LENORMAND <franck.lenormand@nxp.com>

DPAA1 and DPAA2 platforms use SEC ERA 8 and 10 only.

This patch removes code in SDAP and PDCP header related to these
ERA to simplify the codebase:
 - Simplify logic using RTA_SEC_ERA_<> macro
 - Remove era_2_sw_hfn_ovrd dedicated to RTA_SEC_ERA_2
