Series arm64: dts: ti: j7: Add device-tree nodes for MCSPI |

Message

  This series adds device tree nodes for Multi Channel Serial Peripheral
Interface (MCSPI) on J721E, J7200, J721S2 and J784S4 platforms. All the
MCSPI instances are disabled by default and can be enabled through overlays
as required, the changes were tested using spidev loopback test for all
instances and the data verified only for main_spi4 which is connected
internally as slave to mcu_spi2 for all existing J7 devices.

V1->V2: 
  * Address Nishanth's feedback, combine main, mcu domain
  MCSPI node addition changes to single commit per SoC.

Vaishnav,


As per TRM "MCSPI4 is directly connected as a slave to MCU_MCSPI2 by 
default at power-up. MCSPI4 and MCU_MCSPI2 are not pinned out externally".

The above is applicable to J721e/J7200. Similar mapping might be 
existing for j721s2 & j784s4 as well. Add this information in
the commit log. Other than that For the series:
