Will Deacon d4c7b1f9b4 ARM: 6470/1: atomic64: use generic implementation for OABI configurations
The old apcs-gnu ABI doesn't guarantee that double words are allocated
to registers with even alignment, causing the 64-bit exclusive memory
operations to be rejected by the assembler.

This patch requires that CONFIG_AEABI is set in order to use the native
atomic operations and falls back to the generic (spinlock) code otherwise.
