sandbox: specify sizeof(dma_addr_t) == sizeof(phys_addr_t) == 8 on 64BIT
sizeof(dma_addr_t) == 8 shouldn't introduce any functional change, because
we can't have DMA on sandbox. For now it suppresses benign warnings about
mismatched pointer and integer sizes when some headers are included.
sizeof(phys_addr_t) == 8 was already the case on systems with
__x86_64__. As CONFIG_64BIT now is set according to the bitness
of the compiler, we can migrate this fully to Kconfig.
