Provide kernel config variable for default number of devices

[GoogleCodeExporter]

There is module parameter, and corresponding kernel boot parameter,
but it would be usefull to change default value also in kernel config.
Currently by default 1 device is created. For comparission
by default 4 ramdisks are create, and this can be changed in kernel config.
Having such options could make deplyment easier, no module needed, and no
boot loader changes needed.

Thanks.

I'm planning to submit this patch along with other pending patches. In the 
meantime, I've attached the patch which provides this kernel config.
