J721S2 has 8 MCSPI instances in the main domain and 3 instances
in the MCU domain. Add the DT nodes for all the 11 instances and
keep them disabled. MAIN_MCSPI4 is connected as a slave to MCU_MCSPI2
by default at power-up, MAIN_MCSPI4 and MCU_MCSPI2 are not pinned out
externally.

V2->V3:
* Add Keerthy's Reviewed-by.
* Update commit message to mention internal MCSPI loopback.
V1->V2:
* Combine main, mcu domain, MCSPI node addition changes
to single commit.
