This series updates PowerQUICC QMC and TSA drivers to prepare the
support for the QMC HDLC driver.

Patches were previously sent as part of a full feature series:
"Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1]

The full feature series reached the v9 iteration.
The v1 was sent the 07/25/2023 followed by the other iterations
(07/26/2023, 08/09/2023, 08/18/2023, 09/12/2023, 09/22/2023, 09/28/2023,
10/11/23, 11/15/2023) and was ready to be merged in its v8.

The lack of feedback from the Freescale SoC and the Quicc Engine
maintainers (i.e. drivers/soc/fsl/qe/ to which the QMC and TSA drivers
belong) blocks the entire full feature series.
These patches are fixes and improvements to TSA and QMC drivers.
These drivers were previously acked by Li Yang but without any feedback
from Li Yang nor Qiang Zhao the series cannot move forward.

In order to ease the review/merge, the full feature series has been
split and this series contains patches related to the PowerQUICC SoC
part (QMC and TSA).
 - Perform some fixes (patches 1 to 5)
 - Add support for child devices (patch 6)
 - Add QMC dynamic timeslot support (patches 7 to 17)

Compare to the previous iteration:
this v2 series:
- Removes a forward declaration in the driver.
- Adds kernel test robot tags as the issue was detected.
- Adds some missing Cc: stable.
