ARM: cache: remove ARMv3 support code
This is only used by 740t, which is a v4 core and (by my reading of the
datasheet for the CPU) ignores CRm for the cp15 cache flush operation,
making the v4 cache implementation in cache-v4.S sufficient for this
CPU.
Tested with 740T core-tile on Integrator/AP baseboard.
