Subject: [PATCH 0/4] MCSPI clock ID fixes for J7200/J721E/J721S2/J784S4

Hi all,
This series fixes the clock IDs for MCSPI instances across:
1) Main and Wakeup domains in j7200
2) Wakeup domain in j721e
3) Main and wakeup domain in j721s2
4) Main domain in j784s4

In j7200, kernel crashes were observed due to incorrect clock IDs.
In j721e/j721s2/j784s4, there was only a mismatch of clock IDs w.r.t
documentation, however it did not trigger a crash. The clock IDs can be
verified from the below links.

Documentation links:
J7200 - https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j7200/clocks.html
J721E - https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721e/clocks.html
J721S2 - https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721s2/clocks.html
