With the changes to make the LMB reservations persistent, the common memory regions are being added during board init. Remove the now superfluous lmb_init_and_reserve() function.

Changes since V1:
- Removed the replacement of lmb_init_and_reserve() with lmb_add_memory(), as memory gets added during board init.
