NXP/FSL SoC driver updates for v5.1

DPIO driver
- Clean up the remove path in the dpio driver so that successive
  bind/unbind commands behave properly
- Add the ability to automatically create a device link between a
  consumer device on the fsl-mc bus and a supplier one
- Add prefetch to dpio dequeue to improve performance
- Update the type of dpio APIs to align with buffer pool id register
  field

guts driver
- Prevent allocation failure by reuse the machine type data from device
  tree directly
soc: fsl: guts: reuse machine name from device tree

Reuse the string machine from the device tree data structure instead
of duplicating the data again.  This also prevents a potential memory
allocation failure that was not handled previously.  Also fixes an early
put of root device node.
