mm/memblock: introduce PHYS_ADDR_MAX
So far code was using ULLONG_MAX and type casting to obtain a
phys_addr_t with all bits set. The typecast is necessary to silence
compiler warnings on 32-bit platforms.
Use the simpler but still type safe approach "~(phys_addr_t)0" to create a
preprocessor define for all bits set.
