staging: rts5139: fixed issues when config to built-in object

Fixed two issues when CONFIG_RTS5139=y :

  - Makefile doesn't take $(CONFIG_RTS5139). It always uses obj-m and built as
    a loadable module.
  - Rename some symbols with prefix 'rts51x_' to prevent symbol name collisions
    with drivers/staging/rts_pstor when both are configured to be built-in
    objects.
