armv8: LS2080A: Consolidate LS2080A and LS2085A

LS2080A is the primary SoC, and LS2085A is a personality with AIOP
and DPAA DDR. The RDB and QDS boards support both personality. By
detecting the SVR at runtime, a single image per board can support
both SoCs. It gives users flexibility to swtich SoC without the need
to reprogram the board.
