Indexed-count memory management allows addition and removal of contiguous
lmb blocks with a single command. When compared to the series of calls
previously required to manage contiguous blocks, indexed-count decreases
command frequency and reduces risk of buffer overflow.

Changes in v2:
--------------
-[PATCH 1/2]:	-remove potential memory leak when parsing command
		-use u32s drc_index and count instead of u32 ic[]
		 in dlpar_memory
-[PATCH 2/2]:	-use u32s drc_index and count instead of u32 ic[]
		 in dlpar_memory

Changes in v3:
--------------
-[PATCH 1/2]:	-add logic to handle invalid drc_index input
		-update indexed-count trigger to follow naming convention
		-update dlpar_memory to follow kernel if-else style
-[PATCH 2/2]:	-add logic to handle invalid drc_index input

Changes in v4:
--------------
-[PATCH 1/2]:	-add logic to handle kstrdup failure
		-add logic to handle invalid command format
