FMC: create drivers/fmc and toplevel Kconfig question
This commit creates the drivers/fmc directory and puts the necessary hooks for kbuild and kconfig. The code is currently a placeholder that only registers an empty bus.

+
+ FMC (FPGA Mezzanine Carrier) is a mechanical and electrical
+ standard for mezzanine cards that plug into a carrier board.
+ This kernel subsystem supports the matching between carrier
+ and mezzanine based on identifiers stored in the internal I2C
+ EEPROM, as well as having carrier-independent drivers.
+
+ The framework was born outside of the kernel and at this time
+ the off-tree code base is more complete. Code and documentation
+ is at git://ohwr.org/fmc-projects/fmc-bus.git .
