[PATCH 4/5] board: ti: am62px: evm: Set "dfu_alt_info" only if interface is SPI Flash

[Siddharth Vadapalli]

Commit 0af78a1a729d ("board: am62px: 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".
