regulator: core: add const to regulator_ops and fix build error in mc13892
Commit 272e2315fac3 ("regulator: core: add const qualifier to ops in
struct regulator_desc") introduced const qualifier to ops in regulator_desc.
This patch adds 'const' to regulator_ops vars in newly added core APIs
for v3.17-rc1:
- regulator_get_hardware_vsel_register()
- regulator_list_hardware_vsel()
This patch also fix a build error in mc13892-regulator.c due to const
regulator_desc.ops. Modification of regulator_desc.ops' member fields is not
allowed.
