Description

The BOOTPATCHDIR and KERNELPATCHDIR variables can contain multiple directories names separated by spaces as explained in lib/functions/compilation/uboot-patching.sh and lib/functions/compilation/kernel-patching.sh respectively but when calculating hash we were treating it as a single directory name. Also as ATF and crust gets bundled in u-boot, the hash of their patches must also be considered to determine if we need to rebuild u-boot

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.

• [X] Tested by adding removing patches in patch/u-boot/u-boot-sunxi, patch/u-boot/u-boot-sunxi-crust and patch/crust directories and then compiling u-boot for nanopiduo2. U-boot recompiles as expected, which is not the current behavior.
