lsdc currently just ioremaps its PCI BAR with pcim_iomap(). Performing
a region regquest additionally can make the driver more robust.

Replace pcim_iomap() with the managed function pcim_iomap_region() which
performs the request and ioremaps the BAR.

'regquest' ->'request'.

Please avoid typos next time, sound safer otherwise.
