Make mcb depend on HAS_IOMEM and mcb-pci depend on PCI. This fixes build errors
discovered by the 0-day kernel build testing system.

drivers: Introduce MEN Chameleon Bus
The above commit used "default m" which is wrong. New drivers
should never be globally enabled with "default y/m". Whether
this driver makes sense to build on ARM is an independent issue.
Here we delete the "default m" line, which is the equivalent of
"default n".

Add support for MCB over PCI devices. Both PCI attached on-board Chameleon FPGAs
as well as CompactPCI based MCB carrier cards are supported with this driver.

The MCB (MEN Chameleon Bus) is a Bus specific to MEN Mikroelektronik
FPGA based devices. It is used to identify MCB based IP-Cores within
an FPGA and provide the necessary framework for instantiating drivers
for these devices.
