[PATCH v3 3/4] arm64: dts: ti: k3-j721s2: Add MCSPI nodes

[Vaishnav Achath]

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.
