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 .
