[PATCH 2/5] board: ti: j721e: evm: Set "dfu_alt_info" only if interface is SPI Flash

[Siddharth Vadapalli]

Commit 9bd6cc292fa8 ("board: j721e: Define capsule update firmware info")
updated the "dfu_alt_info" variable to support use-cases with SPI Flash.
However, this breaks use-cases where the interface is not SPI Flash ("sf").
Fix this by setting "dfu_alt_info" only when the interface is "sf".
