Eric W. Biederman 91960a46c6 uio: Support 2^MINOR_BITS minors 
register_chrdev limits uio devices to 256 minor numbers which causes
problems on one system I have with 384+ uio devices.  So instead set
UIO_MAX_DEVICES to the maximum number of minors and use
alloc_chrdev_region to reserve the uio minors.

The final result is that the code works the same but the uio driver now
supports any minor the idr allocator comes up with.
