[U-Boot] [PATCH] arm: K3: Fix usage of CONFIG_SYS_K3_KEY

[Lokesh Vutla]

For signing the tiboot3.bin image, an optional KEY file can be passed
using CONFIG_SYS_K3_KEY. Right now, Makefile scripts directly takes
the config value and uses it for signing. This is okay if the build
directory is a sub-directory of source tree, otherwise it fails.
Fix it by using the path relative to the source tree.
