[PATCH V2 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.

Signed-off-by: Nikhil M Jain <n-ja...@ti.com>

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.
