Changes in v4:
- Corrected Copyright year
- Used 'ranges' property in the fss{} node
Changes in v3:
- Added more nodes now that the SCMI interface is ready
Changes in v1:
- switched to non-direct links to TRM updates are automatic
- fixed white space indent issues with a few nodes
- separated out device tree bindings

Add the initial board file for the AM62L3's Evaluation Module.
Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com>
Signed-off-by: Bryan Brattlof <bb@ti.com>
---
Changes from v1:
- switched to non-direct links so TRM updates are automatic
- removed current-speed property from main_uart0
- removed empty reserved-memory{} node
- removed serial2 from aliases{} node
- corrected main_uart0 pinmux
Changes from v2:
- alphabetized phandles
- corrected macros and node names for main_uart0 pinmux node
Changes from v3:
- added and enabled more nodes that have been validated
- added link to data sheet which is now public
Changes in v4:
- Corrected Copyright year
