Ilpo Järvinen 869b9eddf0 mfd: intel-m10-bmc: Add PMCI driver 
Add the mfd driver for the Platform Management Component Interface
(PMCI) based interface of Intel MAX10 BMC controller.

PMCI is a software-visible interface, connected to card BMC which
provided the basic functionality of read/write BMC register. The access
to the register is done indirectly via a hardware controller/bridge
that handles read/write/clear commands and acknowledgments for the
commands.

Previously, intel-m10-bmc provided sysfs under
/sys/bus/spi/devices/... which is generalized in this change because
not all MAX10 BMC appear under SPI anymore.
