[PATCH u-boot-marvell 14/14] tools: kwboot: Set debug flag to 1

From: Pali Rohár <pali at kernel.org>

This should enable BootROM output on UART.

(At least on A385 BootROM this is broken, BootROM ignores this debug
 flag and does not enable its output on UART if some valid image is
 available in SPI-NOR.)
