exec: fix writing to MMIO area with non-power-of-two length

The problem is introduced by commit 2332616 (exec: Support 64-bit
operations in address_space_rw, 2013-07-08).  Before that commit,
memory_access_size would only return 1/2/4.

Since alignment is already handled above, reduce l to the largest
power of two that is smaller than l.

exec: check offset_within_address_space for register subpage

If offset_within_address_space falls in a page, then we register a
subpage. So check offset_within_address_space rather than
offset_within_region.

memory: Provide separate handling of unassigned io ports accesses

Accesses to unassigned io ports shall return -1 on read and be ignored
on write. Ensure these properties via dedicated ops, decoupling us from
the memory core's handling of unassigned accesses.

Revert "memory: Return -1 again on reads from unsigned regions"

This reverts commit 9b8c69243585a32d14b9bb9fcd52c37b0b5a1b71.

The commit was wrong: We only return -1 on invalid accesses, not on
valid but unbacked ones. This broke various corner cases.
