Convert slpc shared data to use iosys_map rather than
plain pointer and save it in the intel_guc_slpc struct.
This will help with in read and update slpc shared data
after the slpc init by abstracting the IO vs system memory.

The asm/iosf_mbi.h header is x86-only. Let's make IOSF_MBI kconfig
selection conditional to x86 and provide a header with stubs for other
architectures. This helps getting i915 available for other
architectures in future.
