commit a0fa0abeb508360bea82a84ce83aea49769641d3 upstream.

Constify a number of static struct resource. The only usage of the
structs are to assign their address to the resources field in the
mfd_cell struct. This allows the compiler to put them in read-only
memory. Done with the help of Coccinelle.
