ide: make remaining built-in only IDE host drivers modular (take 2)
* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
file for probing PCI host drivers registered with IDE core (special case
for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
the ordering in which all IDE host drivers are probed when IDE is built-in
during link time.
* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).
* Move probing of ide-cris (cris arch specific) host driver before cmd640
(x86 arch specific).
* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
(h8300 arch specific).
* Add "probe_vlb" kernel parameter to cmd640 host driver and update
Documentation/ide.txt accordingly.
* Make IDE_ARM config option visible so it can also be disabled if needed.
* Remove bogus comment from ide.c while at it.
v2:
* Fix two issues spotted by Sergei:
- replace ENOMEM error value by ENOENT in ide-h8300 host driver
- fix MODULE_PARM_DESC() in cmd640 host driver
