[PATCH u-boot-marvell 03/11] tools: kwbimage: Set BOOT_FROM by default to SPI

["Marek Behún" <kabel@kernel.org>]

From: Pali Rohár <pali@kernel.org>

kwbimage must have valid blockid member instead of zero value. Thus if
config file does not contain BOOT_FROM command, use by default the value
for SPI booting (which is probably the most common).
