the Intel kbuild bot reports a link failure when IOSF_MBI is built-in but the Merrifield driver is configured as a module. The soc-intel-quirks.h is included for Merrifield platforms, but IOSF_MBI is not selected for that platform.
ld.lld: error: undefined symbol: iosf_mbi_read
referenced by atom.c sound/soc/sof/intel/atom.o:(atom_machine_select) in archive vmlinux.a
This patch forces the use of the fallback static inline when IOSF_MBI is not reachable.
