PCI: use dev_printk when possible

Convert printks to use dev_printk().

I converted pr_debug() to dev_dbg().  Both use KERN_DEBUG and are enabled
only when DEBUG is defined.

I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(),
because dev_dbg() is only enabled when DEBUG is defined.

I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info().  The DBG()
name makes it sound like debug, but it's been enabled forever, so dev_info()
preserves the previous behavior.

I tried to make the resource assignment formats more consistent, e.g.,
  "BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n"
instead of sometimes using "start-end" and sometimes using "size@start".
I'm not attached to one or the other; I'd just like them consistent.
