[PATCH V3 3/8] board: ti: am62x: evm: Update function calls for splash screen

[Nikhil M Jain]

Use spl_dcache_enable, in place of setup_dram, arch_reserve_mmu to set
up pagetable, initialise DRAM and enable Dcache.

V3:
- No change.

V2:
- Use CONFIG_SPL_VIDEO in place of CONFIG_SPL_VIDEO_TIDSS to reserve
  video and  call splash at SPL.
- Check SPL_SPLASH_SCREEN and SPL_BMP before calling splash display.
