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.
