isa: set 24-bit dma_mask for ISA devices
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 legacy drivers, this sets the device dma_mask in preparation for using the actual device with the DMA API so as to eventually not need the NULL hack in dma_alloc_coherent(). 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 4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.
