floppy: move dma setup + drive connect to fdctrl_init_common() 

isa-fdc is completely qdev-ified with this patch applied, all
configuration uses properties.

sysbus-fdc needs dma_channel config fixed.  There is only one user
(mips_jazz) which uses dma channel 0.  Can anyone knowing this
platform suggest how to deal with it?  Is hardcoding fine?
