rockchip64/rk3328: U-Boot v2022.04/07 add setexpr

- aimed at nanopi-r2s and nanopineo3
- impacts:
  - boards (re)using 'nanopi-r2s-rk3328_defconfig' (rk3328)
  and:
  - boards using U-Boot v2022.04 or
  - boards using U-Boot v2022.07
- added explicit dependency on python3-setuptools as (at least) U-Boot
  v2022.04 and v2022.07 fail building due to missing 'distutils' for
  boards that use U-Boot v2022.04 or v2022.07

+
+This will enable bootscripts to calculate load address dynamically during boot,
+removing the need for updating load addresses whenever kernel/initial ramdisk 
+change size.
+
+Also, this will enable bootscripts to find device tree files in folder structures
+that contain a vendor path component, e.g. dtb/allwinnner/...
