[PATCH v2 1/6] bus: arm-cci: use asm unreachable

[Stefan Agner]

Mixing asm and C code is not recommended in a naked function by
gcc and leads to an error when using clang:
  drivers/bus/arm-cci.c:2107:2: error: non-ASM statement in naked
  function is not supported
        unreachable();
        ^

While the function is marked __naked it actually properly return
in asm. There is no need for the unreachable() call.

Changes in v2:
- Don't add assembly ASM_UNREACHABLE, just drop unreachable()
