Kay Sievers 0c81eed4b9 PNP: add all PNP card device id's as individual aliases 
The current PNP combined card + devices module aliase can
never ever match anything, because these values are not available
all at the same time to request a module.

Instead of adding the combined alias, we add the device id's
all as individual aliases. Device id's are exported by the PNP
bus and can now properly used to request the loading of a
matching module.

The module snd-sbawe currently exports aliases, which can never
match anything:
  alias: pnp:cCTLXXXXdCTL0045dCTL0022*
  alias: pnp:cCTLXXXXdCTL0044dCTL0023*
  alias: pnp:cCTLXXXXdCTL0042dCTL0022*
  alias: pnp:cCTLXXXXdCTL0041dCTL0021*
  alias: pnp:cCTLXXXXdCTL0031dCTL0021*
  alias: pnp:cCTL00eddCTL0041dCTL0070*

  alias: pnp:cCTL0039dCTL0031dCTL0021*
  alias: pnp:cCTL0035dCTL0031dCTL0021*

With this patch it exports only the device id's, as properly
matchable aliases:
  alias: pnp:dCTL0070*
  alias: pnp:dCTL0045*
  alias: pnp:dCTL0023*
  alias: pnp:dCTL0044*
  alias: pnp:dCTL0022*
  alias: pnp:dCTL0042*
  alias: pnp:dCTL0041*
  alias: pnp:dCTL0021*
  alias: pnp:dCTL0031*

Now, the exported value of the PNP bus can be used to autoload
a matching module:
  $ modprobe --first-time -n -v pnp:dCTL0045
