platform/x86: intel_scu_ipc: Move intel_scu_ipc.h out of arch/x86/include/asm

This is a platform/x86 library that is mostly being used by other
drivers not directly under arch/x86 anyway (with the exception of the
Intel MID setup code) so it makes sense that it lives under the
platform_data/x86/ directory instead.

No functional changes intended.
