uio_hv_generic: Query the ringbuffer size for device

[ Upstream commit e566ed5b ]

Query the ring buffer size from pre defined table per device
and use that value for allocating the ring buffer for that
device. Keep the size as current default which is 2 MB if
the device doesn't have any preferred ring size.
