mkimage: Add -K to write public keys to an FDT blob
FIT image verification requires public keys. Add a convenient option to mkimage to write the public keys to an FDT blob when it uses then for signing an image. This allows us to use: mkimage -f test.its -K dest.dtb -k keys test.fit and have the signatures written to test.fit and the corresponding public keys written to dest.dtb. Then dest.dtb can be used as the control FDT for U-Boot (CONFIG_OF_CONTROL), thus providing U-Boot with access to the public keys it needs.
