Patch series adds Sierra and Torrent SERDES driver for the SERDES
used in TI's K3 platforms. This SERDES is used by USB3, PCIe and
Ethernet. This series is mostly an adaptation of drivers added in
upstream Linux kernel.

Changes from v4:
1) Dropped `[PATCH v4 01/21] drivers: reset: Add devm_to_reset() to
return dummy "struct reset_ctl"` and will be worked independently of
this series. This was mainly introduced for handling optional reset
which is not mandatory for both Sierra and Torrent.
2) Fixed sectionauthor name for j721e_evm.rst

Changes from v3:
1) Dropped "drivers: reset: Handle gracefully NULL pointers" and added
   "drivers: reset: Add devm_to_reset() to return dummy "struct reset_ctl"
2) Moved documentation from board/ti/j721e/README to doc/board/ti/j721e_evm.rst
3) Adapted Sierra and Torrent driver to 1).

Changes from v2:
1) Re-worked "Handle gracefully NULL pointers" to fix Simons comments
2) Ported the part that allows creating clocks without explicit
sub-nodes in DT from the upstream linux kernel.

Changes from v1:
1) Fixed string comparison strncmp() to remove "=="
2) Added a test for node name comparison to ignore unit address
   in test/dm
3) Added better commit message in "drivers: reset: Handle gracefully
   NULL pointers"
