[PATCH] pcmcia: Add pcmcia_request_threaded_irq()

[Takashi Iwai]

Allow pcmcia drivers to use threaded irq handlers.  The existing
pcmcia_request_irq() helper is calling the new function just with
NULL thread_fn.

Signed-off-by: Takashi Iwai <tiwai@xxxxxxx>

The threaded irq will be used by the rewrite of snd-vxpocket driver.
