kbuild: introduce __init_refok/__initdata_refok to supress section mismatch warnings
Throughout the kernel there are a few legitimite references to init or exit sections. Most of these are covered by the patterns included in modpost but a few nees special attention. To avoid hardcoding a lot of function names in modpost introduce a marker so relevant function/data can be marked. When modpost see a reference to a init/exit function from a function/data marked no warning will be issued.
