config: rockpi-e: use armbian/rkbin default and fix blob paths

The blobs this board pins (rk3328 DDR v1.22, BL31 v1.49) were merged into
armbian/rkbin, which is already the framework's default RKBIN repo. So:

- Drop RKBIN_GIT_URL / RKBIN_GIT_BRANCH overrides (pointed at upstream
  rockchip-linux/rkbin) -- the default armbian/rkbin now carries them.
- Strip the 'bin/' path prefix from DDR_BLOB / BL31_BLOB: armbian/rkbin
  stores blobs flat under rk33/ (matching every other board), so a
  'bin/rk33/...' path would not resolve and u-boot assembly would fail.
- Drop MINILOADER_BLOB: identical to the rk3328 family default and unused
  by the spl-blobs boot map.
