pnp: set the pnp_card dma_mask for use by ISAPnP cards
dma_alloc_coherent() on x86 currently takes a passed in NULL device
pointer to mean that it should allocate an ISA compatible (24-bit) buffer
which is a bit of a hack.
The ALSA ISA drivers are the main consumers of this but have a struct
device in fact readily available.
For the PnP drivers, the specific pnp_dev->dev device pointer is not
always available at the right time so for now we want to pass the
pnp_card->dev instead which is always available. Set its dma_mask in
preparation for doing so.
This does not fix a current bug -- 2.6.26-rc1 stumbled over the NULL hack
in dma_alloc_coherent() but this has already been fixed in commit
