[PATCH v2 0/7] Add u-boot splash screen support for AM62x.

[Nikhil M Jain]

Enable TI Display Subsystem(TIDSS) driver as UCLASS_VIDEO. Enable
splash screen support, to display TI logo during boot-up. Tested
on microtips panel (Model No: 13-101HIEBCAF0-S) supported by AM62x.

The changes in patch 4 depends on the patch sent for addition of
am62x.env file to set environment variables for AM62x.
