MIPS: OCTEON: Get rid of CONFIG_CAVIUM_OCTEON_HW_FIX_UNALIGNED
When you turn it off, the kernel is unusable, so get rid of the option and always allow unaligned access. The Octeon specific memcpy intentionally does unaligned accesses and it must not fault.

- help
- Configure the Octeon hardware to automatically fix unaligned loads
- and stores. Normally unaligned accesses are fixed using a kernel
- exception handler. This option enables the hardware automatic fixups,
- which requires only an extra 3 cycles. Disable this option if you
- are running code that relies on address exceptions on unaligned
- accesses.
