ACPI: platform-profile: Drop const qualifier for cur_profile
Drop the const qualifier from the static global cur_profile pointer declaration. This is a preparation patch for passing the cur_profile pointer as parameter to the profile_get() and profile_set() callbacks so that drivers dynamically allocating their driver-data struct, with their platform_profile_handler struct embedded, can use this pointer to get to their driver-data. Note this also requires dropping the const from the pprof platform_profile_register() function argument. Dropping this const is not a problem, non of the queued up consumers of platform_profile_register() actually pass in a const pointer.
