ide: pass number of ports to ide_host_{alloc,add}() (v2)
Pass number of ports to ide_host_{alloc,add}() and then update
all users accordingly.
v2:
- drop no longer needed NULL initializers in buddha.c, cmd640.c and gayle.c
(noticed by Sergei)
There should be no functional changes caused by this patch.
