Staging: vme: Use A24 when requesting slave resource
When requesting slave resources A16 addressing mode flag is used to find available windows. Since the ca91cx42 bridge only supports two A16 slave windows but four are requested, the driver fails to initialize. The flag has been changed to A24, which is supported by all slave windows.
