memblock tests: zero-extend simulated memory addresses
Converting a 32-bit pointer directly to the 64-bit phys_addr_t can
sign-extend it when BUILD=32 is used. A dummy allocation above 2 GiB
then gets registered at an address different from its unsigned pointer
value. The low-address tests compare that value against the registered
range and fail once the earlier maximum-address free test is fixed.
Convert through uintptr_t when registering and reporting dummy memory.
This preserves the pointer bits and agrees with the simulator __pa()
conversion and the allocation tests.
