mfd: kempld-core: Constify variables that point to const structure
Add const to the declaration of various local variables of type
kempld_platform_data for which the referenced value is always only
dereferenced or passed to a const parameter, to record the fact that
kempld_platform_data_generic is declared as const.
The semantic match that finds this issue is as follows:
