mfd: core: make platform_data pointer const in struct

Commit-Message
The content of the platform_data of a struct mfd_cell is simply passed on to the platform_device_add_data() call in mfd_add_device() . platform_device_add_data() already handles the data behind that pointer as const and also uses kmemdup to create a copy of the data before handing that copy over to the newly created platform-device, so there is no reason to not extend this to struct mfd_cell, as the old copy in the mfd_cell will be stale anyway. This allows to pass structs gathered from of_device_get_match_data() as platform-data to sub-devices - which is retrieved as const already. Signed-off-by: Heiko Stuebner <heiko@...>
