ALSA: sc6000: Use explicit cast for __iomem pointer

Browse Source 
The recent optimization to store an iomem pointer in card's
private_data field caused sparse warnings.  Although they are
practically harmless, add the explicit cast for avoiding the spurious
warnings.

Fixes: 9b7843d1e1 ("ALSA: sc6000: Assign vport directly on card's private_data")
