kcore: add kclist types
Presently, kclist_add() only eats start address and size as its arguments. Considering to make kclist dynamically reconfigulable, it's necessary to know which kclists are for System RAM and which are not. This patch add kclist types as KCORE_RAM KCORE_VMALLOC KCORE_TEXT KCORE_OTHER This "type" is used in a patch following this for detecting KCORE_RAM.
