Subject: [PATCH 6/8] mfd: stmpe: Constify static struct resource

Constify a couple of static struct resource. The only usage of the
structs is 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.
