Kernel - Restore the 64KB max. IO size limit

* Some drivers and part of the kernel are dependent on an implicit
  64KB maximum IO size limit

* Explicitely set it to 64KB (or MAXPHYS if it is smaller) for devices
  which do not report a default value

* This should fix ATA DMA errors reported in issue #2342
