[U-Boot] [PATCH] bootm: fdt: Use panic() instead of hang() when presented with a bad image

[Alex Kiernan]

When the image which bootm is given can't be booted, call panic with
the error message rather than printf/hang so that we can recover from
broken images via a bootcount mechanism. If hang on failure is still
required then CONFIG_PANIC_HANG can still be enabled.
