Subject: [PATCH 2/5] regulator: fixed: Constify static regulator_ops

The only usage of fixed_voltage_ops and fixed_voltage_clkenabled_ops is
to assign their address the ops field in the regulator_desc struct,
which is a const pointer. Make them const to allow the compiler to put
them in read-only memory.
