crypto: ccp - Constify 'dev_vdata' member

Browse Source 
sp_device->dev_vdata points to only const data (see 'static const struct
sp_dev_vdata dev_vdata'), so can be made pointer to const for code
safety.

Update also sp_get_acpi_version() function which returns this pointer to
'pointer to const' for code readability, even though it is not needed.

On the other hand, do not touch similar function sp_get_of_version()
because it will be immediately removed in next patches.
