Subject: [PATCH 0/8] drivers/mfd: Constify static struct resource

Constify a number of static struct resource to allow the compiler to put
them in read-only memory. Typically, the only usage of these is to assign
their address to the resources field in the mfd_cell struct, which is a
const pointer (a few drivers also read the value of the start field).

I went through the rest of the static instances of struct resource in
drivers/mfd and all of them are either directly modified by the driver
or has its address passed to mfd_add_devices() which takes a non-const
pointer.

The series is compile-tested only.

I split this into patches per maintainer, I'll happily split it (or squash
it) some other way if that's preferable.
