[PATCH 0/3] AM62x SK EVM DT Sync + OSPI Support

[Dhruva Gole]

* Sync the AM62x DTS files with the linux kernel.
* Also add configs necessary to enable ospi in uboot
* Add support for booting from OSPI Flash.

All changes have been tested on the AM62x SK EVM and the board
successfully reached u-boot prompt using OSPI Flash:

Also the board was tested to boot till linux kernel after the DT sync
changes. Hence verifying that the changes are valid.
