Maybe an option would be to provide two cpu_v7_switch_mm implementations (one with the errata and one without). Then the system can start with the simple implementation. Once the boot as progressed far enough to know, that the hardware is affected by the errata, it could switch to the implementation with the flushing.
Or rather the opposite, as if the kernel itself is thumb-compiled, it most probably will have no chance to progress enough to switch to the correct implementation before hanging.
