There currently are multiple allocation API's in the LMB module. There are a couple of API's for allocating memory(lmb_alloc() and lmb_alloc_base()), and then there are two for requesting a reservation for a particular memory region (lmb_reserve() and lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will cater to all types of allocation requests and replace lmb_reserve() and lmb_alloc_addr() with the new API. Moreover, the lmb_reserve() API is pretty similar to the lmb_alloc_addr() API, with the one difference being that the lmb_reserve() API allows for reserving any address passed to it -- the address need not be part of the LMB memory map. The lmb_alloc_addr() does check that the address being requested is actually part of the LMB memory map. There is no need to support reserving memory regions which are outside the LMB memory map. Remove the lmb_reserve() API functionality and use the functionality provided by lmb_alloc_addr() instead. The lmb_alloc_addr() will check if the requested address is part of the LMB memory map and return an error if not.
