board: ti: am64: select NAND overlay if HSE card present 

Since we are using overlay for A53 SPL and A53 u-boot the
SPL must select the NAND overlay from the FIT image if
HSE card is present.

For simplicity sake, we only check if a card is present or not in
the HSE (High Speed Expansion) slot to determine if we need to
use NAND overlay.
