exec.c: Remove out of date comment

Remove an out of date comment: this comment used to be attached to
cpu_register_physical_memory_log(), before commit 0f0cb164

inserted a couple of other functions between the comment and its function.
It is in any case obsolete since (a) the function arguments it refers
to have been replaced with a single MemoryRegionSection* argument and
(b) the inability to handle regions whose offset_within_address_space
and offset_within_region aren't equally aligned was fixed as part of
the rewrite of this code.

For RAM, 'size' must be a multiple of the target page size.
If (phys_offset & ~TARGET_PAGE_MASK) != 0, then it is an
io memory page. The address used when calling the IO function is
the offset from the start of the region, plus region_offset. Both
start_addr and region_offset are rounded down to a page boundary
before calculating this offset. This should not be a problem unless
the low bits of start_addr and region_offset differ. */
