[PATCH V3 04/10] board: ti: am62x: evm: Add necessary functions to call splash screen

[Nikhil M Jain]

To enable splash screen at SPL, call methods to reserve memory for video
and enable cache, and splash_display to display bmp image.

Signed-off-by: Nikhil M Jain <n-jain1 at ti.com>

V3:
- Remove function call for dram setup and set pagetable.
- Call splash display only if SPLASH_SCREEN is defined.

V2:
- No change.
