These vendor_data structures are only stored in the vendor field of
the uart_amba_port structure, as defined in the same file, and this
field is declared as const.  Thus the vendor_data structures can be
const too.

Done with the help of Coccinelle.

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>

There are some other vendor_data structures in the same file, but
they are used in a different way.
