Change lmb to use phys_size_t/phys_addr_t
This updates the lmb code to use phys_size_t and phys_addr_t instead of unsigned long. Other code which interacts with this code, like getenv_bootm_size() is also updated. Booted on MPC8641HPCN, build-tested ppc, arm, mips. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
