pciconf: Fix alignments of device memory and I/O resources

Resources must be their-size-aligned. While here:
- Switch *align variable from int to more suitable integer types.
- Make some conditions clearer (NFC).

pciconf: Fix round-up logics for total sizes of bridge resources

The previous ones are valid only if alignments are 4K or 1M,
for I/O or memory, respectively.
pciconf: Sort resource windows in order of decreasing alignment
instead of size.

Consider pci0 has two ppb's. ppb0 has a memory window larger in
size, but smaller in alignment. ppb1 has one smaller in size, but
larger in alignment.

In this case, the memory window of ppb1 must be allocated earlier.
Otherwise, total size of required memory exceeds pci0's mem_total,
in general, due to padding region.
